Adams Rite MS1951W-X5X - Series MS® Deadlock - Radius with Weatherstrip Faceplate

The stainless steel MS1951W-X5X Series MS® Deadlock - Radius w/ Weatherstrip Faceplate utilizes a laminated stainless steel hookbolt, to provide maximum security for a sliding narrow stile aluminum door.

This Stainless Steel Deadbolt is activated by a pivot mechanism.


The MS1951W-X5X stainless steel deadbolt answers the security need of sliding 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. The over-center MS locking action of this stainless steel deadbolt assures that forced entry attempts to pry the door in any direction, up, down, or sideways, will be defeated.


360° turn of key or thumbturn projects or retracts the counterbalanced bolt. Key can be removed only when bolt is in a positively locked or unlocked position. Lock accepts any standard 1" [25.4 mm] length, 1-5/32" [29.4 mm] diameter mortise cylinder with MS® cam such as the 4036 Mortise Cylinder or thumbturn such as the 4066 Thumbturn, available separately. The MS1951W-X5X stainless steel deadbolt accepts cylinder on either or both sides
