Case

Steel with corrosion-resistant plating. 1" x 6" x depth. (Depth varies by backset)

Function

The MS® Hookbolt 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 in provided in a hook shape to resist the parting motion of sliding door and jamb.  The overcenter MS® locking action assures that forced entry attempts to pry the door in any direction, up, down or sideways, will be defeated.

Bolt

5/8" x 1-3/8" with 13/16” throw. Eight ply laminated stainless steel with Alumina-Ceramic core defeats any hacksaw attack (including so called super hacksaws) while hook shape repels prybar attempts to “spread” door from jamb or lift it off its track.

Strike

See catalog for dimensions of strike slot which can be cut in metal jamb. Trim plate, box strike and armored strike are also available. 

Operation

360° turn of key or thumbturn throws or retracts the counterbalanced bolt. Key can be removed only when bolt is in a positively locked or unlocked position. Lock accepts any standard 1-5/32" diameter mortise cylinder or thumbturn from either or both sides. Cylinder must have MS® dimensioned cam. 

Cylinder Cam

MS1850S-050 Series locks are operable by any standard 1-5/32" diameter mortise cylinder with special MS® dimensioned cam. Cylinders with MS® cams can be readily obtained from most cylinder manufacturers. See catalog for cylinder make and trim ring information.

Options

Cylinder backset and faceplate finish and shape (radiused, flat or bevel cross-section to match door nose) must be specified.

Standard Package

Individually boxed with machine screws for mounting. Cylinders and/or thumbturn available at extra cost. Shipping weight: 1-1/2 lbs.
