Matte Black Round Door Knob With Lock

What this door knob is

This is a round door knob with a built-in lock, finished in matte black. The body is zinc alloy, which gives it a solid feel and a smooth, low-sheen surface that resists showing fingerprints. It is sold as a single knob, and keys are included, so it works as a locking knob for a bedroom, bathroom, office or any interior door where you want privacy and a keyed entry.

The round shape keeps the look simple and traditional. Matte black pairs well with dark hardware elsewhere in a room, and it also stands out against white or light wood doors.

Sizes and fit

Check your door thickness before you buy. This knob is not for doors thicker than 1-13/16 in (46 mm). If your door is thicker, the latch and screws will not line up correctly.

The 2.09 in (53 mm) knob diameter gives you a comfortable grip without taking up much visual space. The overall 6.4 x 2.52 in (163 x 64 mm) size covers the knob, rose and latch assembly.

Color

Matte black is the only color offered for this knob. It is a flat, non-reflective black that reads as modern or classic depending on the rest of your hardware. If you are matching other fixtures in the room, look for matte black rather than gloss or satin black for the closest match.

How to fit it

The knob fixes with screws through the latch face and strike plate. That means the latch goes into the edge of the door, and the strike plate goes into the door frame, with screws holding each in place. You will need a standard screwdriver and a drill for the latch and strike plate openings if they are not already cut.

Before installing, confirm the door is no thicker than 1-13/16 in (46 mm). Line up the latch with the existing bore hole, then attach the knob and rose on each side of the door. Test the lock and the keys before you close the door for the first time.

Because keys are included, you can lock the door from the outside. Keep a spare key in a safe place in case the door is locked by accident.

Care

Wipe the knob with a dry cloth. Avoid wet cloths, sprays or abrasive cleaners, which can dull the matte finish over time. A quick dry wipe now and then keeps the surface even and free of dust.
