SDC's UniFLEX™ electric strike products feature an interchangeable faceplate design.

Why should you care? The interchangeable faceplate design allows for these strikes to meet a variety of applications. Simply change the faceplate to meet your specific needs!

SDC's 55 series and 45 series electric strikes are available in a variety of configurations to accommodate several types of mechanical locksets and door and frame styles - as well as failsafe and failsecure applications.

SDC’s 55 series 3/4” latchbolt electric strikes are heavy duty. They are designed for installation in hollow metal frames for access control of cylindrical locksets, mortise locksets with or without deadbolts and mortise exit devices. 55 series strikes accept 3/4” throw latchbolts and up to 1” throw deadbolts. The choice of six application faceplates eliminates the need for centerline relocation, making them ideal for new or retrofit, high security access control applications.

SDC’s 45 series 5/8” latchbolt electric strikes are centerline latch entry strikes designed for use with cylindrical locksets and mortise locksets without deadbolt for both metal and wood frames. 45 series strikes accept 5/8” throw latchbolts or up to ¾” throw latchbolts with 1/8” door gap. Centerline latch entry strikes require the latch to enter at the strike “centerline” located exactly between the top and bottom of the strike faceplate.

As an additional benefit, we have created all-in-one part numbers that come with the electric strike and three faceplates for the most common applications.

SDC's AUTO series operators can power all of SDC's motorized ELR products.

Why should you care?
AUTO series operators eliminates the need for a separate power supply to power latch retraction products with it's own built in 1 Amp+ power supply! 

Since 2012, when SDC launched the QuietDuo™ LR100 series – the first retrofit motorized ELR kits to convert mechanical exit devices – we’ve been “quietly” leading in electric latch retraction upgrades for access control.

SDC now provides these same high performing motorized ELR features in the new American Made S5000 series storefront and S4000 series industrial electrified exit devices.

The new electrified devices, in addition to the existing LR100 series retrofit ELR kits and 7600 series motorized ELR mortise locks are conveniently compatible with low energy operators including SDC's AUTO series.

Highlights of our AUTO series operators include:

SDC’s approach to exit devices is focused on providing locksmiths, dealers and integrators with opportunities in retrofitting existing mechanical devices to electronic – for integration into access control systems while maintaining security, fire and life safety compliance in a cost-effective manner.
