Schlage Commercial S40SAT619 Privacy Knob Saturn Satin Nickel

Product Description

The SCHLAGE COMMERCIAL S40SAT619 is an S Series privacy knob lockset in a Saturn style, finished in satin nickel. This lockset is designed for interior privacy applications such as bathrooms and bedrooms where a turn-button or push-button locking mechanism is required from the inside without a keyed exterior. It ships complete with a 16-203 latch and a 10-001 strike plate, giving installers everything needed for a standard door prep. The satin nickel finish provides a clean, neutral appearance that coordinates with a wide range of commercial and residential hardware. Knob operation is smooth and consistent with the S Series mechanical platform.

This lockset is suited for light commercial, multi-family, and institutional interior doors where privacy function is specified. Typical installations include restrooms, offices, hotel guest rooms, and similar occupancies. The included latch and strike are factory-matched to the knob assembly, simplifying the rough-in process for door hardware installers and commercial finish carpenters working on standard hollow-core or solid wood interior doors.
