Hager Hinge 3550WTN26D Withnell Lever Office Lock Satin Chrome

Product Description

The HAGER HINGE 3550WTN26D is a Withnell lever-style office cylindrical lockset finished in satin chrome (26D). Cylindrical locksets are the standard choice for commercial and light commercial interior doors where a keyed office function is required — the door locks from the outside with a key and remains accessible from the inside at all times. The 26D satin chrome finish resists tarnish and blends with standard commercial hardware schedules. The Withnell lever design meets ADA lever requirements typical of commercial door hardware specifications. This unit ships as a single assembly and is installed by locksmiths, carpenters, or general contractors during door hardware rough-in or retrofit work.

The 3550WTN26D is suited for interior office doors in commercial, institutional, and light-industrial settings. The office function makes it appropriate for private offices, storage rooms, and similar spaces where controlled access is needed from one side. The cylindrical form factor fits standard door prep — a 2.125-inch crossbore with a standard backset — making it a practical replacement or new-construction option for commercial interior door schedules.

Installation Notes

Installation is performed by a licensed locksmith, finish carpenter, or qualified contractor. Power to any access-control or electric-strike systems at the door must be shut off before beginning work. Follow the door manufacturer's prep specifications for backset and crossbore dimensions to ensure proper fit. Local building codes, including ADA accessibility requirements, may govern lever style and hardware function selection in commercial occupancies.
