MS1950, MS1950-X5X Series MS® Deadlocks

The stainless steel MS1950 Series MS® Deadlock utilizes a laminated stainless steel bolt, to provide maximum security for a single leaf narrow stile aluminum door.
The stainless steel MS1950-X5X Series MS® Deadlock utilizes a laminated stainless steel hookbolt, to provide maximum security for a sliding narrow stile aluminum door.
Both are activated by a pivot mechanism.

Function: 

A huge bolt of laminated stainless steel, nearly 3" long, activated by an uncomplicated pivot mechanism, has made the basic MS1950 MS® Deadlock the standard of the narrow stile aluminum door industry. The length of this bolt provides maximum security for a single leaf door, even a very tall and flexible one or an installation where the gap between the door and jamb is greater than it should be.
The stainless steel MS1950-X5X Series MS® Deadlock 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 assures that forced entry attempts to pry the door in any direction, up, down, or sideways, will be defeated.

Operation:

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.
