Tulip Passage Knob Lockset

The Master Lock TUO0415/T6P is a satin-nickel passage knob set designed for interior doors that do not require locking. Its tulip styling suits residential hallways, closets and bedrooms where a simple turn-to-open action is preferred.

ANSI Grade 3 mechanical limits

The lockset meets ANSI Grade 3 standards, the baseline rating for residential hardware. It is tested for lighter duty cycles than Grade 2 or Grade 1 products and is not intended for high-traffic commercial entries or exterior doors that demand stronger latch bolts and tougher finish durability.

Upgrade from basic tubular latches

This set replaces a plain tubular latch or an older knob that has worn loose or lost its finish. The adjustable 2 3/8 to 2 3/4 in. backset fits most standard door preparations without re-boring. The jump is worth it when you want a coordinated tulip style, a satin nickel surface that resists tarnish better than polished brass, and a Grade 3 certified mechanism in one package.

What does Grade 3 mean for daily use on an interior door?
