The SCHLAGE COMMERCIAL B660R613 is a Grade 1 single cylinder deadbolt designed for commercial and institutional door applications. It features a Large Format Interchangeable Core (LFIC) with a C keyway, bitted to factory specification, and ships with a 12296 latch and 10094 strike included. The oil rubbed bronze finish suits installations where darker architectural hardware is specified. Grade 1 is the highest ANSI/BHMA performance rating for deadbolts, making this hardware appropriate for high-traffic entry doors in commercial, multi-family, and institutional settings. Licensed locksmiths, security contractors, and commercial door hardware installers are the primary trades for this product.
This deadbolt is intended for commercial-grade door applications including office buildings, institutional facilities, multi-family residential common areas, and similar environments where key control and physical security are priorities. The LFIC cylinder format allows the core to be removed and replaced with a controlled key using a control key, without disassembly of the lockset, which is a standard requirement in master-key and key-control programs. The included latch and strike are matched components for this unit.
Designed as a Grade 1 commercial single cylinder deadbolt with Large Format Interchangeable Core for use in commercial and institutional door hardware applications where LFIC key control systems are in use.
Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with ANSI door prep standards and LFIC key control procedures. Confirm door thickness and backset requirements before installation. De-energize any access control or electrified hardware connected to the door before beginning work. Core removal and key control enrollment must follow the governing master key system protocols for the facility.
