Original Makita A28084 — Release Catch (listed also as A280‑84). This genuine Makita release catch is the small magazine latch (item 54 in Makita’s AT638 parts diagram) that secures and releases the stapler magazine.
Fits Makita AT638 / AT638A 1/4" narrow‑crown staplers (staple length 15–38 mm) and is shown on official Makita parts listings as the replacement for that magazine latch (A0711‑0581).
Made as an original Makita service part to match factory fit and function, this release catch restores reliable magazine retention and staple feeding without having to replace larger assemblies. As one of the small Makita parts you’ll commonly replace on a stapler, it’s a direct, drop‑in swap to get your tool back to normal operation.
If you need a single replacement component among other power tool parts, this release catch is the correct factory part for the AT638
