Schlage Commercial S51PSAT605 Entry Knob Lock Bright Brass

Product Description

The SCHLAGE COMMERCIAL S51PSAT605 is an S Series entry knob lockset with Saturn trim, designed for commercial and institutional door hardware applications. It features a C keyway, keyed different (KD) cylinder, and ships complete with a 16-203 latch and 10-001 strike. The bright brass (605) finish provides a clean, traditional appearance suited to interior and exterior commercial doors. This lockset is installed by licensed locksmiths, commercial door hardware contractors, or qualified facilities maintenance technicians. The entry function allows free egress from the inside while requiring a key for entry from the outside.

The S51PSAT605 is intended for commercial and institutional buildings where a standard entry function is required on interior corridors, office suites, or perimeter doors. The Saturn knob design and C keyway make it compatible with commercial key systems that use Schlage C keyway pinning. Supplied as a single unit, it is well suited for new construction and retrofit installations where a keyed-different configuration is specified.
