Note: Wood casing can easily be applied to Timely frames. This requires a frame without Casing Retainer Clips. Specify frames with nail holes and oval slots (NHOS) only Wood casing is then installed over the frame face using a nail gun or trim head screws. Casing profile must provide back clearance for screw heads used to install frame.

Fire Ratings: Wood casing must be applied with hot melt glue or contact adhesive on 90 minute rated frames and on all glazed openings with 45 minute or 60 minute rating. On all other fire rated frames, wood casing can be applied with nails or finish head screws on jambs and mullions.
