See “Hospital Stop”.
The side of an opening that requires a key, card reader, or controlled access authority to open the door.
A document prepared by material suppliers that clearly lists each opening and the materials being supplied for that opening. The shop drawing is reviewed by the contractor and architect for compliance with the plans and specifications. The contractor also uses the approved shop drawings to determine framing requirements, installation requirements and job scheduling. Shop drawings are often supplied with product submittal sheets to provide a clear description of the materials being supplied by the sub-contractor.
A portion of a door frame adjacent to the door opening prepared for glass or ceramic glazing. In some cases the “sidelight” portion of the frame may contain a door panel or other material.
This is the lowest component of a sidelight opening. For a stepped sidelight, there are two or more sidelight sills.
This is the outermost vertical component of a sidelight opening. For a stepped sidelight, the vertical member farthest away from the door is the Sidelight upright. Vertical components between the lights are “stepped sidelight mullions” since they have a mullion profile between the light areas.
Sidelight, Extended Sill
The extended sill sidelight is a full height sidelight with a sill dimension larger than 2" up to 12". The extended sill is made of vertical panels attached to the mullion and sidelight upright with mullion brackets. The casing on the extended sill sidelight projects to the floor and a jamb section with mullion notches creates the cover for the sill. The sill has a mullion cut casing between the mullion and the sidelight upright .
Sill casing is any casing applied to a sidelight sill. Sill casing is mitered one end and straight cut with cope/notch as required depending on casing type. Casing for Extended sill is mullion cut with cope/notch as required depending on casing type.
A piece of 18 ga. insert material formed similar to a mullion insert that is anchored to the floor. The sidelight sill slips over the sill channel and is anchored to the channel.
Sill – Door Opening
The bottom treatment of a door opening, usually a threshold and/or a door bottom. The sill is part of the sealing system for an opening if required.
Sill – Sidelight, Borrowed Light Frame
The portion of a sidelight or borrowed light frame running parallel to the floor at the bottom of the frame.
A door that only swings in one direction out of an opening and rests against the stop on the door frame when closed.
A door frame prepared for hardware for a single door.
A door frame with a profile showing only one rabbet with the stop extending to the opposite face of the frame.
A term referring to a frame with only one door.
A door hung on rollers that roll along a track at the head. This may be a single sliding door, a pair of doors (see “Bi-pass Door”) or multiple doors in multiple tracks in the same opening.
Smoke Control Door/Frame
A fire rated assembly (20 min.) of door frame and hardware with fire rated perimeter sealant to prevent smoke from travelling through the opening when the door is in the closed position.
Smoke Gasket (Smoke Seal)
Any approved sealant substance used to seal an opening to prevent the passage of smoke from one side to the other when the door is in the closed position.
A sound door is the most important part of a sound rated assembly. A sound rated assembly (STC Rated) consists of the door, frame and edge sealing devices on all four edges. Sound doors differ from standard doors because of special core materials or additional thickness required to prevent sound transmission through the opening.
A sealing material used to fill the gap between a door and frame that has been tested and proven to be an effective component to reduce the travel of sound from one side of the opening to the other.
A piece of metal, usually stainless steel placed at the bottom of a door frame to facilitate easy cleaning.
A volume of documents that clearly defines the extent of a contract between a contractor and the building owner’s representative. The specifications explain all the terms of the contract and continue with the acceptable products, applications, performance and warranties.
A connection of two pieces of material of identical shape to form one continuous run.
Spliced Extended Sill
An extended sill made up of two pieces on each side held together with TA-25 reinforcements. The splice is required when the width of the sill area exceeds 12' 1".
If a header exceeds 12' 1" it must be spliced. A square cut is made at the splice location, usually at a mullion. A spliced header has the same frame profile on both header pieces.
If a jamb exceeds 12' 1" it must be spliced. A square cut is made at the splice location, usually at a mullion. A spliced jamb header has the same frame profile on both jamb pieces on each side of the frame.
A door frame with a profile that consists of two parts that can be adjusted for various wall conditions or be separated if it the door unit is to be pre-hung.
If a header must be made up of two different profiles, it is called a split header. This occurs if a no stop sidelight is combined with a standard door frame. The header is split at the mullion.
If a jamb must be made up of two different profiles, it is called a split jamb. This occurs if a no stop transom is combined with a standard door frame. The Jamb is split at the mullion. (Not to be confused with a wood split jamb which is a two piece wood jamb similar to an adjustable steel frame).
A spreader is a piece of solid material cut to a precise length used to maintain a consistent spacing between jambs or headers when installing. The spreader is used when anchoring the frame when the actual door is not available. A spreader is commonly used when installing hollow metal frames. This spreader is different than the spreader bars used to support a frame during shipping. The welded in spreader bars are never to be used in place of the installation spreader.
The joining of two pieces of metal in a specific location using the heat generated by electrical resistance to melt the metal and form the weld. Copper contacts firmly clamp the material at the spot of the weld.
One or two light gauge steel angles welded to the bottom of a welded hollow metal frame to support the frame and prevent wracking during shipment. Shipping spreader bars are not intended to be used as a reference and must be removed prior to installing the frame. A separate template board is used to maintain door width when plumbing and leveling the frame.
A hinge that has a spring assembly in the barrel for closing the door. As the door is opened, the spring is wound creating the tension necessary to close the door. Spring hinges are adjustable for spring power but have no other adjustment for back check, latching speed or adjustable opening and closing force. Spring hinges are not designed as load bearing hinges and should be used at only the middle or bottom hinge locations on a door.
A door’s vertical edge that has not been beveled and is exactly at 90° from the door faces. Also called a “book” edge when the door is full width (not nominal) width.
An opening or shape having all corners at a perfect 90° angle and equal diagonal measurements.
The process of aligning perimeter parts so that the opening has 4 90° angles. One way to determine if an opening is square is to measure the distance between the corners diagonally. The distance from the top left corner to the lower right corner must be exactly the same as the distance from the bottom left corner to the top right corner.
An opening (Door, Frame, Hardware, Edge Seal) that has been tested using ASTM methods to meet a particular Sound Transmission Classification. The assembly must bear a label certifying the test standard and the STC rating.
STC (Sound Transmission Class) Rating
A value given to a part of a building’s interior structure based on measurement of the structure’s ability to reduce the passage of sound from one side of the structure to another. The structure may be a wall, a door and frame unit or a glazed unit. The higher the STC rating, the less sound is transmitted from one side of the structure to the other.
Casing material made of steel used to trim out a Timely frame concealing the fasteners. TA-8 and TA-30 are both steel casings.
A door frame made primarily of steel. A steel frame may be cased using steel, aluminum, PVC, or wood but the structural components are made of steel.
A component commonly used in buildings as a framework for walls and partitions. Steel studs vary in gage of metal from 20 ga. to 24 ga. and in width from 2" up to 12". Steel studs are used as the framework to attach other wall components for structural, sound or blocking. Once wall materials are in place, the wall is covered with drywall board.
Steel Stud Anchor
A piece of formed steel used to attached a welded or knocked down hollow metal masonry frame to the steel stud framework prior to the application of drywall.
Steel Stud Track
A component in steel stud framing with an inside dimension the same as the outside dimension of a steel stud. Steel stud track sections are used when horizontal members are required because the studs, running vertically, will nest easily inside the track and can be fastened with a screw. Because track sections are normally 1/8" wider than stud sections, the actual wall thickness of a steel stud partition is a minimum of 1/8" wider than the stud dimension.
Lengths of jamb, insert or assembled mullions supplied in 10' 1" or 12' 1" lengths to be used by dealers with fabrication shops when building frames, sidelights and borrowed lights in their shop.
A piece of formed steel used on the inside of certain types of hollow metal doors to maintain rigidity and uniform thickness.
The vertical portion of a stile and rail door (either wood, fiberglass or metal) that is clearly shown as a separate piece. In some cases, the stiles are approximately 4" – 6" but many vary depending on the style of door. In some cases, the stile width limits the type of locking hardware that can be used on the door.
A term used to describe a stile and rail constructed door that has narrow stiles usually less than 3" in width. Stile and rail doors are most often made of wood, aluminum, steel or fiberglass.
A term used to describe a stile and rail constructed door that has wide stiles, usually larger than 3" in width. Stile and rail doors are most often made of wood, aluminum, steel or fiberglass.
The portion of the door frame in extending from the rabbet that creates a solid barrier for the door to close against.
The surface on a door frame that rests against the face of the door when the door is in the closed position.
A special frame modification intended to eliminate inside corner areas that are susceptible to accumulation of dirt and debris. The stop portion of a door frame is trimmed back about 6" above the floor and the frame filled in to create a flat.
A frame incorporating a stop portion that is removable. The stop may be removable for glazing purposes or for special hardware installation.
A piece of metal used to protect the surface of the door frame and trim when the door swings closed and to provide a recess to accept the latching or deadbolt mechanism.
- Lipped strike – a strike with a lip that extends beyond the frame face and trim to prevent damage from a latchbolt
- No Lip strike – a strike with no lip used to accept a deadbolt mechanism. A deadbolt is mechanically operated when the door is in the closed postition
- Dustproof Strike – a strike with a spring loaded plunger that depresses when the deadbolt is inserted. When the door is in the unlocked position, the plunger extends to the strike surface preventing foreign debris from getting into the strike housing
- Electric Strike – a strike used to control access from a remote location. Electric strikes have a solenoid that retracts the strike mechanism or engages the latchbolt allowing entry only when the strike is activated or if someone has authorization to operate the locking hardware with a key
- Roller Latch Strike – A lipped strike with a recessed area instead of a hole allowing the roller to extend into the strike and maintain position until opened
- Bullet Catch Strike - A lipped strike with a recessed area instead of a hole allowing the round “bullet” to extend into the strike and maintain position until opened
A recessed area formed by an emboss process on a steel frame used to install the strike so it is flush with the frame surface. (See "Emboss").
A blank plate the same shape as a strike emboss or mortise used to fill a frame preparation that is not going to be used.
Strike, Full Lip
A strike common in residential construction that is the same height across its width. A Full lip strike is much easier to mortise in wood jambs than a ‘T’ shaped strike. For a Timely frame, a full lip strike can be used on 1 3/4" frames only. The Timely Full Lip strike prep is supplied with Tinnerman clips allowing the strike to be applied to the steel frame using the wood screws shipped with the strike .
For single door openings, it is the vertical member of a door frame that contains one or more strikes. The jamb opposite the hinge jamb is the strike jamb even though it may not be prepared for a strike.
For single door openings, it is the vertical member of a sidelight frame that contains one or more strikes. The mullion opposite the hinge jamb or hinge mullion is the strike mullion even though it may not be prepared for a strike.
A recessed area formed by chiseling (wood doors and frames) cutting, and/or welding steel doors and frames) on a steel frame used to install the strike so it is flush with the frame surface.
A piece of solid metal attached to the inside of a door frame that is drilled and tapped for a surface mounted strike. The reinforcement provides the necessary depth of threads to adequately secure the strike.
Sub Frame (Sub Buck, Rough Buck)
A framework applied to a finished opening in a structure that serves as a suitable anchorage for a door frame when the material or location of the opening prohibits a standard installation. This is a common application for a Timely frame in masonry walls.
A folio of documents which includes the project shop drawings and door schedules specifically referring to the product data sheets for all products being supplied by a sub contractor or material supplier.
Any piece of operating hardware or door accessories applied to the surface of the door frame or casing instead of being installed in an emboss or mortise.
A round or square bolt applied to the surface of a door with a strike normally surface mounted on the frame used to lock down an inactive door in lieu of a flush bolt which is mortised into the door.
Surface Mounted Closer
A door closer applied to the surface of the door and frame. The frame must be provided with adequate reinforcement for the screws used to attach the closer and arm assembly.
Surface Mounted Stop/Holder
A hardware apparatus used to limit the arc of travel of at door that is installed on the surface of the door and frame instead of being installed in a mortise.
Surface Sliding Door
See “Barn Door”.
The arc or path of a door as it travels from its closed position to its maximum open position.
