Mortise Lock Component Selection & Compatibility

Storm door mortise lock systems require precise component matching—cylinder keying, latch projection, strike alignment, and handle geometry must correspond to the original lock body. Technicians and contractors replace individual components during routine service or full system upgrades. Identifying the lock manufacturer and model ensures first-call resolution and eliminates callback risk.

OEM Replacement Components for Direct Fit Installation

Replace individual mortise lock components without removing or modifying the lock body. Identify your lock manufacturer—Marks, Larson, Andersen—and select matching cylinders, latches, strike plates, or handle hardware. Components ship with keying references and installation specifications to confirm correct fit before on-site installation.

Cylinder Keying and Latch Projection Specifications

Storm door mortise cylinders vary by key blank profile and cam design. Latch projection and strike plate spacing differ between 1-1/8" and 1-3/4" door frames. Measure existing assembly, verify cylinder keyway, and confirm latch throw before ordering. Mismatched components prevent door closure and compromise security.
