Falcon T521BD D 622 Grade 1 Office Cylindrical Lock

Product Description

The FALCON T521BD D 622 is a Grade 1 office-function cylindrical lock designed for commercial door hardware applications. It features an SFIC (Small Format Interchangeable Core) prep, meaning the lock ships without a core installed and is ready to accept a standard small format interchangeable core from compatible keying systems. The Dane lever handle is paired with a standard rose trim and finished in Flat Black Coated (finish code 622). The non-handed design allows installation on doors swinging in either direction without modification.

This lock is suited for office-function applications in commercial and institutional buildings where a lever-operated lock is required on interior office doors. The office function allows free egress from the inside while the outside lever is locked by default, a common configuration for private offices, storage rooms, and similar spaces. Licensed locksmiths and commercial door hardware installers typically specify and fit this product during new construction or retrofit projects.

Key Features

• ANSI Grade 1 heavy-duty rating for commercial applications
• SFIC prep accepts small format interchangeable cores for flexible keying system integration

Compatibility

Designed as an OEM-style replacement or new-installation cylindrical lock for commercial doors requiring a Grade 1 office-function lock with SFIC core preparation.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware installer familiar with cylindrical lock prep standards. Verify the door bore diameter and cross-bore spacing match the lock specifications before installation. The SFIC core must be sourced separately and installed according to the core manufacturer's instructions. Always confirm the door is plumb and the latch aligns properly with the strike plate before completing installation.
