Description
The Arrow AM41-LB is a heavy-duty mortise lock body designed for commercial and institutional doors. Built with heavy gauge steel and zinc dichromate finish, it resists corrosion and handles high-traffic environments. Field-reversible handing means you can adapt it to either side without disassembly, solving installation flexibility challenges.
