Overview
A keyed entry knob and lock set in matte black stainless steel, rated ANSI Grade 3 and tested past 200,000 cycles. All three included keys open the same lock, and the latch adjusts for standard 60mm or 70mm backsets. Suited to bedroom, bathroom or exterior doors that need a basic locking knob.
One buyer flagged a rotation issue within days of use, so this reads as a knob that performs well for most people but is not immune to the occasional unit with alignment trouble.
- ANSI Grade 3 rated, tested past 200,000 cycles
- 3 keys included, all cut alike
- Fits 1-3/8 to 1-3/4 inch door thickness
- Matte black stainless steel finish
Who it's for
Homeowners and renters who want a simple keyed lock for an interior bedroom or bathroom door, or a lower-cost option for a secondary exterior door. Not aimed at buyers who need commercial-grade hardware or a keyless system.
Pros and cons
- Installs without a professional in under an hour
- Adjustable latch fits most standard door thicknesses
- All three keys open the same lock
- Matte black finish resists corrosion
- Internal hardware feels light duty to some buyers
- One reported case of inconsistent lock rotation
- Screws are packed inside the knob, easy to overlook
Performance notes
The latch adjusts between a 2-3/8 inch and 2-3/4 inch backset and fits standard door thickness from 1-3/8 to 1-3/4 inch, so it covers most residential doors without extra parts. All three keys are cut alike, useful when the same lock needs to open from more than one set. The stainless steel knob and copper lock cylinder are rated to ANSI Grade 3 and tested past 200,000 open and close cycles, though one reviewer's experience with inconsistent locking rotation suggests some unit to unit variation.
