The DRA-1 DIN Rail Adapter is designed for quick attachment and detachment of various surface-mount devices onto a standard 35mm DIN rail. Four #8-32 mounting holes are located on the face of the Adapter support numerous models. The Adapter and grip plate are made of 20-gauge steel and assembled as one unit for durability. Constructed with two high-tension extension springs, the DRA-1 Adapter will securely fasten surface-mount enclosures to a standard 35mm DIN rail. The mounting hole pattern matches a standard Time Mark surface-mount enclosure.
