The Lock Behind The System

Since 1972, SDC has manufactured popular electrified access control hardware like bolt locks, strikes, EMLocks® and egress devices in America while most of our larger competitors manufacture overseas. Designed, engineered and built in America means SDC products are readily available with standard one week lead times for most products. With a robust toolbox of over 35,000 access and egress control components, SDC's code compliant products form turnkey solutions for almost any door opening imagined.

Electric Bolt Locks
Spacesaver® bolt locks were the world's first right angle electric bolt locks and represent a fundamental innovation in electric locking technology for access control applications.

Electric Strikes
UniFLEX™ electric strikes were the first to feature interchangeable faceplates and field reversibility for failsafe or failsecure operation. The interchangeable design allows SDC to provide multi-application kits to meet common applications.

Electromagnetic Locks
EMLock® is the industry standard in electromagnetic locks. EMLocks were the first electromagnetic locks to incorporate an interlocking quick mount design and captive mounting screws to simplify installation.

Egress Devices
SureExit® pressure sense request-to-exit bars were the first to allow the immediate release of electromagnetic locks, and still the only tri-failsafe exit bar available on the market today.
