Hager 3550 26D Wtn Sfic Grade 2 Cylindrical Lock

Product Description

The HAGER 3550 26D WTN SFIC is a Grade 2 cylindrical lockset configured for entry and office applications. It ships as an SFIC (Small Format Interchangeable Core) prep without a core installed, allowing the installing technician or facility locksmith to drop in a compatible SFIC core on site. The lever style is the Withnell design, mounted on a rose trim, and the finish is Satin Chrome (26D). This lock is a standard cylindrical chassis designed for commercial and light-institutional door hardware installations.

This lockset is suited for interior office doors and controlled-entry doors in commercial buildings where a keyed entry function is required. The SFIC prep configuration makes it a practical choice for facilities that use a master key or access control program built around small format interchangeable cores, since cores can be swapped without removing the lock body from the door. It is typically installed by licensed locksmiths, door hardware specialists, or commercial carpenters working on new construction or renovation projects.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware technician familiar with cylindrical lock prep standards. Verify the door prep diameter and backset before installing to ensure the chassis seats correctly. The SFIC core must be sourced and installed separately after the lock body is mounted. Follow applicable building code requirements and hardware schedule specifications for the project.
