Imperial USA TH1100 Series Deadbolt Face Plate Radius w/ Weatherstrip

It measures 6-7/8 x 1 inches. That is the standard narrow stile deadbolt face plate footprint on Imperial TH1100 series locks, so measure the existing plate on your door: if your current plate is the same 6-7/8 by 1 inch and has a radius (rounded) end, this drops straight in. A square-end plate of the same size will not match the routed pocket edge.

No. This is the face plate alone, the trim piece that screws to the edge of the stile over the deadbolt. If the lock itself is worn or the bolt is binding, you need the TH1101 mortise deadbolt lock, not just this plate.

Two: AL aluminum and DU duronodic (dark bronze). Pick the one that matches the rest of the door hardware on the opening, since a lock face plate sits right on the visible edge of the stile and a mismatch shows when the door is open.

Match the routing in the door stile. Aluminum storefront doors are prepped either with a radius (rounded end) pocket or a square end, and the plate has to follow that cut. The TH1101-FP5 is the radius version with weatherstrip; if your stile pocket has square corners, you need the square face plate instead.

It seals the gap at the lock edge on an exterior aluminum entrance door, so air and water do not track through the deadbolt pocket. If you are replacing a plate on a storefront door that whistles or leaks at the lock stile, the weatherstrip version is the one to order rather than the plain radius plate.

Yes, the TH1101-FP5 is a commercial part, intended for glass aluminum entrance doors rather than residential wood doors. Property managers standardizing storefront openings can stock it as a spare, since the face plate is the piece that gets bent or scratched long before the lock body fails.
