Sargent MD-106-26D Auxiliary Key Control 8400 8600 Cvr

Product Description

The SARGENT MD-106-26D is an auxiliary key control unit designed for use with 8400 and 8600 CVR series exit devices. It houses a single-bitted LA keyway mortise cylinder, allowing facility managers and door hardware installers to maintain controlled key access alongside existing exit hardware. The satin chrome finish (626/US26D) provides corrosion resistance and a neutral appearance that integrates cleanly into commercial door assemblies. This unit is installed by licensed door hardware professionals and locksmiths working on commercial egress systems that require both exit capability and keyed access management.

The MD-106-26D is intended for installation on AD, MD, and WD door configurations paired with 8400 and 8600 CVR exit devices. It is suited for commercial and institutional facilities where controlled access must be maintained at exit points without compromising egress compliance. Typical applications include office buildings, schools, healthcare facilities, and other commercial spaces requiring coordinated key control at panic hardware-equipped doors.
