What Is a Mortise Lock and Why Do So Many Arvada Properties Still Use Them?
A mortise lock is a self-contained lock body that sits inside a mortise — a precisely routed pocket — in the door stile. The exposed hardware you see on the face of the door (the trim, escutcheon plate, knobs or lever handles) is separate from the internal mechanism, which is why mortise lock sets can be dressed up or kept utilitarian without changing how the lock itself functions. Common in American construction from the late 1800s through the 1970s, they remain the hardware of choice for many architects and building owners who want a robust, repairable lock that can carry a wide range of optional functions: passage, privacy, classroom, storeroom, and more. Brands like Corbin Russwin mortise lock hardware and Baldwin mortise lock products became mainstays in institutional and upscale residential construction precisely because the internal components could be serviced without replacing the entire door prep.
In Arvada specifically, properties in the Ralston Valley corridor, the historic Olde Town district, and many of the post-war apartment complexes on West 60th Avenue still carry original or early-replacement mortise hardware. Owners often want to preserve that look — and the security it provides — rather than re-bore the door for a cylindrical lockset, which would weaken the door stile and change the door's character. Our technicians understand both the mechanical and aesthetic reasons to keep mortise hardware on these doors, and we stock a broad selection of compatible replacement bodies, cylinders, and trim to make that possible.
