8590 ASA 4-7/8" T-Strike Plate Template

Woodhaven 8590 T-Strike Plate Router Template – ASA Standard Size

Routing a clean, accurate T-strike plate mortise in a door jamb is one of those tasks that looks simple but goes wrong fast without the right jig. The Woodhaven 8590 T-Strike Plate Router Template clamps directly to the jamb with no nail holes, no surface damage, and no layout guesswork. Two screw-in indexing pins set your backset quickly and keep the jig square to the fence for consistent results every time.

Built for trim carpenters and dedicated woodworkers who need reliable, repeatable door jamb router template results, the 8590 handles the ASA standard 1-1/4" x 4-7/8" T-strike plate size used on the vast majority of residential door hardware. Pair it with our Lockset Plate Jigs for a complete door strike plate mortise jig setup in a single pass.
