How to Choose Multi-Point Locks for Aluminum Doors

The best multi-point lock is not the model with the most locking points. It is the system that fits the aluminum profile, operates smoothly, controls gasket compression, survives the intended environment, and performs as part of a tested doorset.

The Role of Adjustable Keeps in Multi-Point Lock Systems

Adjustable keeps are not minor frame accessories. They determine whether hooks, rollers, latches, and deadbolts enter their receiving points correctly, whether the gasket receives even compression, and whether a multi-point locking system operates smoothly after installation tolerances and door movement begin to appear.

Why Multi-Point Locks Must Match the Correct Strike Plates

A multi-point lock is not a collection of independent locking points. It is a coordinated mechanical system. When the strike plates do not match the lock geometry, the gearbox absorbs the error, users force the handle, seals compress unevenly, and an expensive door assembly begins failing from day one.
