Hager 3550 26D Arc Sfic Grade 2 Cylindrical Lock

Product Description

The HAGER 3550 26D ARC 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 to field-insert the appropriate SFIC core from a compatible keying system. The lever trim is the Archer style mounted on a rose base and finished in satin chrome (26D). This lockset is intended for commercial and light-institutional door hardware applications and is typically installed by a licensed locksmith or commercial door hardware technician.

This lockset is suited for interior office doors and exterior entry doors in light commercial, multi-tenant, or institutional settings where a standardized interchangeable core keying system is already in use. The SFIC prep design means the hardware can be installed and the building occupied before the final core is inserted, which simplifies large-scale keying projects. The satin chrome finish coordinates with standard commercial hardware schedules.

Key Features

• Grade 2 cylindrical lock construction for commercial and light-institutional use

Compatibility

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with cylindrical lock bore patterns and SFIC keying systems. Verify the door prep matches the required cross-bore and latch-bore dimensions before installation. The SFIC core must be ordered and inserted separately using the appropriate control key for the core system in use. Consult local building codes and the door manufacturer specifications for fire-rated door hardware requirements.
