Monday, December 23rd, featured our first annual Ugly Sweater Day. Pictured are semi-finalists and eventual $50.00 winner - Courtney Peña. Her ensemble featured a digital loop of holiday tunes sung by cats going - "Meow, meow, meow, meow" - into infinity. She probably banked more cash in bribes not to wear it again next year.

Back to Basics: Electric Bolt Locks

Before SDC invented the 90° electric lock in the 1970’s, installation of electric bolt locks was costly, often requiring the cutting of studs and considerable reconstruction of door frames. Our Spacesaver® bolt lock design is a fundamental access control innovation now used worldwide. They install in any standard frame and most door stiles with a simple mortise cutout. The rotating bolt design makes tampering or cutting very difficult. An automatic relock ball switch keeps the bolt retracted when the door is open.

Additionally, they are field adjustable for wide door gaps and bidirectional for use on swinging or sliding doors. The Spacesaver® FS23M series is still the only dual-failsafe electric bolt lock in the industry.

Today, our comprehensive line of bolt locks use the same practical, yet pioneering approach to meeting access control requirements for safety, security and code compliance.
