INTERIOR For interior applications in concrete or CMU walls, the frame can be installed over the finished wall using Tapcon screws or applied to a steel sub frame supplied by Timely. The sub frame is attached to the opening using Tapcon screws or powder actuated fasteners and the door frame is secured to the sub frame using self drilling screws.
EXTERIOR Do not use Timely frames in exterior masonry applications unless an overhang is used or created. Frames must be galvanized and installed using a steel sub frame.
NOTE: You can use a Timely frame for your EXTERIOR INSTALLATIONS as long you take precautions to FLASH THE FRAME CORRECTLY.
