This Delaney Hardware Saxon privacy door knob, model 102T-SA-CS-US15, is constructed from metal, often durable zinc, and finished in satin nickel. Designed for interior doors, it features a privacy function allowing it to be locked from the inside, typically via a push-button or turn-button, with an emergency release mechanism on the exterior side. It meets ANSI Standard A156.2 Grade 3, indicating suitability for standard residential use and providing fundamental operational security and durability. The knob is equipped with an adjustable backset and is designed to fit wood or metal doors between 1-3/8 inches and 1-3/4 inches thick. Although privacy knobs do not use an external key for locking, the inclusion of a KW1 keyway specification indicates its compatibility within the broader Delaney Hardware line, often used for re-keyable cylinders in keyed functions to allow for master or construction keying.
