LSDA Mortise Lock, Grade 1, MLF Series
MLF mortise locks offer excellent strength and security. An oversized escutcheon makes this an excellent retrofit product and easily covers previous installations of other products such as Schlage mortise locks, Sergent mortise locks, and Yale mortise locks. The lever design is compliant with ADA and other accessibility codes. These locks are recommended for use on exterior and interior doors. Typical applications include Offices, Hospitals, Schools, Multi-Family Buildings, Industrial Sites, and Public Buildings.
