Description
The Adams Rite 4900 Series Mortise Deadlatch delivers flexible traffic control for commercial doors requiring free entrance at certain times and exit-only at others. A reverse key turn holds the bolt retracted, enabling two-way passage when needed. Built with a steel case, corrosion-resistant plating, and a solid brass latch bolt, this lock suits facilities managing variable access patterns.
This mortise lock retrofits existing 4500/4700 preparations and interchanges with MS1850A or MS1850S deadbolts of matching backset and faceplate. It includes both flat and radius faceplates, a strike, and mounting hardware. As an authorized Adams Rite dealer, E.D. Locks offers expert guidance on cylinder selection, backset sizing, and installation. Contact sales@edlocks.com or 1-877-207-6067 for compatibility verification and support.
