Enclosure Door Stops
Enclosure door stops are mechanical accessories designed to hold electrical enclosure doors securely in an open position during installation, inspection, or maintenance. These components help prevent unintended door movement caused by wind, vibration, or gravity, improving safety and accessibility when working inside control panels and electrical cabinets.
RSP Supply carries a full line of enclosure door stops and stop arm kits compatible with a wide range of wall-mount, free-stand, and floor-mount enclosures. Many kits are designed for use with standard Type 4, 4X, and Type 12 enclosures that feature horizontally opening doors and sufficient internal clearance. Door stop assemblies are engineered to integrate without compromising enclosure integrity or environmental ratings.
Material options include painted steel and Type 316 stainless steel to support both indoor and outdoor applications. Stainless steel door stop kits provide enhanced corrosion resistance and are well suited for washdown areas, coastal environments, and other corrosive conditions. Certain free-stand and floor-mount door stop kits are designed to hold doors open to a minimum of 90 degrees and meet Telcordia GR-CORE vertical door retainer requirements for wind loading.
