Quiet Duo™ LR100 Latch Retraction & Dogging Field Retrofit Kits

With only 450mA inrush, SDC’s UL approved Quiet Duo LR100 series field retrofit kits provide simultaneous electric latch retraction and dogging with automatic retriggering for major brand mechanical exit devices, eliminating costly exit device replacement while providing access control and sustained dogging (pushpad depression) for sustained push-pull applications. In addition to field retrofit kits, SDC also offers factory installed options.
