There are two other SDC products sold at Home Security Store.The PSB560V - Pressure Sense Bar offers the highest level of safety and reliability. The Sure Exit® proprietary tri-failsafe technology is activated by slight pressure, which immediately releases a magnetic lock or activates a delay. Thirdly, Home Security Store carries the MSB550V - Mechanical Switch Bar.Equipped with a mechanical switch activated by only 1/8” bar movement, the MSB550V provides an economical alternative where the safety release attributes of sense bars is not required.

After working in the door and hardware industry, Arthur Geringer founded SDC in 1972 when he created a more effective electronic locking device than what was already on the market. Today, SDC is based out of a 20,000 square foot factory in Westlake Village, California. The company holds many patents and trademarks.
