Selection Factors
- Center-to-center hole spacing (the critical fit dimension)
- Overall length and projection from the door
- Knob vs pull, and matching knobs to pulls across a kitchen
- Finish matched to faucets and appliances
- Cabinet style (modern, transitional, traditional)
- Grip comfort and edge profile
Installation Notes
Drill the door or drawer front to the center-to-center spacing using a template, then fix with machine screws (8-32) sized to the panel thickness. For retrofits, match the existing hole spacing or use an adjustable backplate.
