1090 - Spacesaver® Bolt Locks by SDC

Fully concealed and easily installed in 1.75" (4.44cm) frame or door stile

The Spacesaver®, first designed and patented by SDC, is a fundamental innovation in electric locking technology for access control applications.

The stainless steel bolt projects at right angles to the lock mechanism, allowing installation of Spacesaver® locks, by means of a simple cutout, in virtually any standard 1.75" frame, or in most door lock stiles. With the entire lock concealed, esthetic acceptability is complete, security is greater and installation in old or new construction is fast, easy and economical.

Stainless Steel Bolt

Greater security is provided by the 0.625" (1.6cm) diamter solid stainless steel bolt. The bolt rotates freely, making attempts to tamper or cut extremely difficult.

Specification Grade Solenoid

All Spacesaver® lock solenoids are manufactured by SDC to precision specifications. SDC solenoids are capable of superior overall performance in both force and longevity, providing years of service compared to commercial grade solenoids.

Code Compliant

Classified in accordance with Uniform Building Code standard 7-2, "Fire Test for Door Assemblies".


SDC Spacesaver® locks may be mounted in the frame header, side jamb or door lock stile.

Field Adjustable Auto-Relock Switch

The automatic relock switch keeps the bolt retracted while the door is open. The door depresses the ball switch assembly on closure, causing the bolt to project automatically, locking the door. In addition, the ball switch assembly is bidirectional, permitting the locks to be used on swinging and sliding doors.

1091A Failsafe:

The 1091A is locked when energized. Recommended for safety applications, it is intended that the door unlock automatically when power is interrupted by the access control, power failure or signal from a fire life safety system.

- Bolt Throw 0.75" (19.05mm)

1091AD Deadlocking Failsafe:

The 1091ADL is equipped with a deadlocking mechanism that prevents the bolt from being tampered with an pried to unlock. The 1091ADL has all the operational features of the 1091A (above) and is recommended for failsafe applications requiring a higher level of security.

- Bolt throw 0.75" (19.05mm)
