The RIXSON 6-436 630 is a concealed, low-profile overhead door stop designed for aluminum storefront door applications. Part of the Checkmate product line, it features a concealed channel mount that keeps hardware out of sight while firmly limiting door travel. Constructed from stainless steel with a satin stainless steel finish, this stop is built for durability in high-traffic commercial entryways. It is installed by commercial door and hardware technicians as part of a complete aluminum storefront door assembly.
This stop is suited for single or double acting doors in both interior and exterior applications. The low-profile concealed channel integrates directly into the door frame or door body, making it a clean-looking solution for storefronts, office entries, and commercial glass door systems where exposed hardware is undesirable. Its design accommodates the demands of frequent door operation in light commercial and retail environments.
Designed for installation in aluminum storefront doors, accommodating single or double acting, interior or exterior door configurations.
Installation should be performed by a qualified door and hardware technician familiar with aluminum storefront systems. Ensure the door is fully closed and any closer or operator is depressurized or disabled before beginning work. The concealed channel requires precise routing or fitting within the door stile — follow the manufacturer installation template to achieve proper alignment. Verify that door swing clearance and stop positioning comply with applicable building codes and accessibility requirements before finalizing the installation.
