A tubular ball lock (also called knob lock or tubular knobset) is a cylindrical lock mechanism installed through a single bore in the door face. The ball/knob design offers a classic rounded grip, while the tubular chassis allows faster, simpler installation than mortise or heavy cylindrical locks.
Keyed Entry (ET) function means:
Outside: Requires key to unlock
Inside: Thumb-turn or push-button for instant exit
Use case: Offices, storage rooms, restrooms, any interior door requiring controlled access
This lock fits standard residential door prep:
Cross bore: 2-1/8"
Edge bore: 1"
Backset: adjustable 2-3/8" or 2-3/4"
If you’re replacing an existing interior lockset, this is a direct drop-in replacement — no drilling or rework required.

FAQ
Q: Is ANSI Grade 3 secure enough for a front door?
A: For a main entry door, we recommend Grade 2 or higher. Grade 3 is perfect for interior doors (bedrooms, bathrooms, closets) but not for exterior entry points.
Q: Can I install this myself without a handyman?
A: Yes. The lock includes all screws and a step-by-step guide. If your door has standard residential prep (2-1/8" cross bore), installation takes about 10 minutes with a Phillips screwdriver.
Q: What’s the difference between Privacy and Entry function?
A: Privacy has a push/turn button inside (bathroom) with an emergency release outside. Entry uses a key on the outside and a turn knob inside (bedroom or home office).
Q: Do you offer keyed alike for multiple locks?
A: Yes. Select “Keyed Alike” and enter the number of locks. We’ll ship all locks keyed the same — ideal for landlords or homeowners.
Q: What finish matches matte black fixtures?
A: Our US19 Matte Black is an industry-standard finish that matches most major brands like Schlage and Kwikset.
