The Adams Rite 3090-01-626 is a deadlatch for aluminum and narrow-stile doors - the lock case that sits inside the stile where a conventional lock will not fit. Adams Rite effectively defined this category, and the dimensions are what the rest of the industry builds to.
Compatibility: Fits standard Adams Rite door preparation. Backset, door thickness, handing and finish all have to match your opening - confirm them before ordering.
