When it comes to electrifying existing exit devices, dealers often face a tough choice: replace costly hardware or deal with bulky, high-draw solenoids that may reduce reliability over time. But what if you could achieve electric latch retraction (ELR) without removing the device—or breaking the budget?
SDC’s LR100 Series Retrofit Electric Latch Retraction Kits solve this problem with a smart, efficient upgrade path. Designed for seamless compatibility with major brands, these motor-driven kits offer lower current draw, quieter operation, and a faster install—ideal for both fire-rated and panic-rated openings.
