The RSG Security DH series fire door holders are constructed of the finest materials and workmanship available. The door holder is made of durable die-cast metal and offered in a high luster powdercoat finish.

Other features include standard dual voltage ac or dc inputs of 12 & 24V, 24 & 120V, and 24 & 220V models. While reducing stocking requirements, model 24120 draws a mere .020 ma. @ 24VDC, lowering overall job costs. In large installations the cost savings can be substantial.
