Schlage Commercial S51RSAT626 Entry Lockset Saturn Satin Chrome

Product Description

The SCHLAGE COMMERCIAL S51RSAT626 is a cylindrical entry lockset built for commercial and institutional door applications. It features the C keyway configuration in a keyed-different (KD) setup, meaning each unit ships with its own unique key cut. The large-format cylinder design accommodates interchangeable core systems used in commercial keying programs. The Saturn-style trim gives the lockset a clean, low-profile look suited to office and light institutional environments. Included hardware consists of a 16-203 latch and a 10-001 strike. The satin chrome finish (626) resists corrosion and blends with standard commercial hardware. This unit is sold individually and is installed by licensed locksmiths or commercial door hardware professionals.

This lockset is intended for commercial entry doors where a cylindrical lock chassis is required. The S Series platform is a common specification in office buildings, multi-family corridors, educational facilities, and light institutional settings. The C keyway makes it compatible with commercial master key systems built around that keyway profile. The included latch and strike allow for a complete installation on standard commercial door preps without sourcing additional trim hardware. The large-format cylinder accommodates interchangeable core inserts where facility keying programs demand field re-keying flexibility.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with cylindrical lock chassis alignment and strike prep requirements. Verify door thickness and backset measurement before installation to confirm latch compatibility. De-energize any access control or electric strike circuits tied to the door before beginning work. Consult local building and fire codes regarding hardware function requirements for designated egress paths.
