SDC MSB550V48 MSB550 Series 48" Mechanical Switch Bar, Dull Aluminum

Ensure safe, code-compliant egress without sacrificing aesthetics or reliability with the Security Door Controls MSB550 Series 48in Mechanical Switch Bar. Designed for access control and security applications, the MSB550V48 releases electromagnetic door locks with a light, quiet press — thanks to a microswitch that activates with only 1/8in (0.125in) of bar travel. The heavy-duty aluminum extrusion and all-metal mounting assembly prevent sagging or misalignment on high-use doors, reducing service calls and downtime. With a low 1.875in projection, this mechanical exit bar blends into glass storefronts and finished interiors while providing clear "PUSH TO EXIT" messaging for building occupants. The 48in length is field-cuttable to fit a variety of openings and ships UL and CSFM listed for commercial installations. Ideal for security, access control, surveillance integration, and monitoring systems, the MSB550V48 delivers dependable egress for hospitals, offices, retail, and institutional facilities.
