At 48 inches in length, it fits standard double-door or wide single-door frames. Qualified door hardware technicians and security system integrators are the primary installers. The device is sold as an individual unit and is categorized under exit devices for trade procurement purposes.

The MSB550V48 is suited for commercial doors requiring compliant panic hardware with integrated switching capability.
