The SD-991A-D1Q converts cylindrical lock sets into an electronic access-controlled locking system. It is a fail-secure door strike and has a simple two-wire, non-polarised connection making installation easy.

Equipped with a stainless steel keeper for strength and long life, the Mini Door Strike is perfect for office-type applications. A shallow, reversible design allows it to be installed on most metal doors and either left-hand or right-hand doors.

The SD-991A-D1Q includes a stainless steel no-cut and silver-coloured aluminum low-cut strike plate.
