Passage knob for interior doors

The Master Lock BAO0415/T6P is a mechanical passage knob set finished in satin nickel with a ball-style grip. It is intended for interior rooms where no locking function is required such as hallways closets or utility spaces. The set meets ANSI Grade 3 standards for residential duty.

Steel construction with adjustable backset

The lock body is made of steel and fits standard crossbore preparations of 2 1/8 inches. An adjustable latch accommodates backsets between 2 3/8 and 2 3/4 inches while the included strike measures 2 1/4 by 1 3/4 inches. Installation suits doors ranging from 1 3/8 to 1 3/4 inches thick.

Replaces worn or mismatched knobs

This set upgrades tired hardware on existing pre-bored doors without changing the bore or mortise. The jump is worth it when the current knob binds finishes clash or the latch no longer engages cleanly. It does not serve entries that need a keyed or privacy function.
