The SCHLAGE COMMERCIAL B560P643E is a Grade 2 single cylinder deadbolt designed for commercial and light commercial door applications. It ships with a C keyway configuration, keyed different (KD), and is keyed alike to a KA4 group. The assembly includes a 12287 latch and a 10094 strike plate, making it a complete deadbolt kit ready for installation. The Aged Bronze finish provides a consistent, durable appearance suited to institutional and commercial environments. Licensed locksmiths, commercial door hardware installers, and general contractors handle installation in standard hollow metal or wood door frames.
This deadbolt is suited for commercial interiors, light commercial entryways, multi-family residential corridors, and institutional applications where Grade 2 security hardware is specified. The C keyway is widely used in commercial master-key systems. The included latch and strike allow direct installation without sourcing additional trim hardware. The KA4 keying designation means this unit is factory-keyed to match other KA4-designated locks in the same order, simplifying key management on larger projects.
Designed as an OEM-style replacement or new-installation deadbolt for commercial and light commercial door assemblies requiring Grade 2 single cylinder hardware with a C keyway. Compatible with standard door prep for deadbolts per ANSI backset specifications.
Installation should be performed by a licensed locksmith or qualified door hardware installer familiar with ANSI/BHMA grade requirements and local building codes. Power is not required for this mechanical deadbolt. Verify door thickness and backset dimensions before installation to ensure proper latch and strike alignment. Do not overtighten mounting screws, as this can affect cylinder operation and latch throw.
