Adams Rite MS1851SNSI-450-628 MS Series ANSI Deadlock Hook Bolt, 1-1/2" Backset, Radius Faceplate, Clear Anodized

The MS Hookbolt deadlock answers the security need of sliding glass doors in commercial, industrial and institutional buildings. The mechanism is identical to the widely used Maximum Security swinging door lock, except that the massive laminated bolt is provided in a hook shape to resist the parting motion of sliding door and jamb.
