How to Replace Cabinet Hardware

Decide between knobs (one hole) and pulls (two holes). If switching from knobs to pulls, you'll need to drill new holes. Measure the center-to-center (CC) distance of your existing pulls (if applicable). Count all the cabinets and drawers that need hardware — typically 20-30 pieces for an average kitchen. Order a few extras in case of defects.

Unscrew all existing knobs or pulls from the inside of the cabinet door or drawer front. If the old hardware has been painted over, score around the base with a utility knife first to prevent paint chipping. Save one old screw — you'll use it to check the length of the new screws. Set old hardware aside (donate it if it's still in good condition).

If you're switching from pulls to knobs (going from two holes to one) or changing the CC distance, fill the old holes with wood filler. Press filler in with a putty knife, let it dry, then sand smooth. Touch up with matching paint. If simply swapping knobs for knobs or matching-CC pulls, skip this step — you'll reuse the existing holes.

If drilling new holes, use a cabinet hardware jig (like the Liberty Align Right Jig). The jig clamps to the door or drawer edge and positions the drill guide at the exact center. Mark your desired hole positions through the jig. Apply painter's tape over the mark (this prevents the drill from chipping paint or laminate), then drill through the tape with the correct size bit — typically 3/16 inch for standard hardware screws.

Insert the machine screw through the back of the cabinet door or drawer front. Thread the knob or pull onto the screw from the front and tighten. For pulls, insert both screws and start both before tightening either one — this ensures the pull sits straight. Tighten until snug — don't overtighten or you'll strip the screw hole or crack the door panel.

If the screws that came with your hardware are too long (they stick out inside the cabinet) or too short (they don't reach through the door), buy replacement machine screws at the hardware store. Common sizes are #8-32 thread in various lengths. Bring one of the included screws to match the thread. Drawer fronts are usually thicker than doors, so you may need two different screw lengths.

After installing all hardware, close all doors and drawers and step back to check alignment. All pulls should be at the same height and orientation. All knobs should be centered consistently. If any are off, loosen and adjust. The visual consistency of aligned hardware is what separates a professional-looking kitchen from a DIY one.
