Alpha Doors & Security installed a concealed floor-mounted door closer (floor spring) in the concrete subfloor for heavy commercial glass and metal doors, providing invisible self-closing operation with no visible overhead hardware. Our technicians core-drilled the floor slab, set the recessed cement box, and installed the adjustable-speed floor closer mechanism for smooth, reliable performance. This concealed floor closer meets fire code and ADA requirements while maintaining the premium frameless aesthetic of high-end commercial storefronts and lobby entrances.
