How to Measure Cabinet Pull Center-to-Center (CTC)
Cabinet pull replacement starts with the distance between the mounting holes. Matching this measurement helps you reuse existing holes and avoid unnecessary drilling.
What CTC Means
CTC means center-to-center: the distance from the center of one mounting hole to the center of the other.
Use the millimeter CTC shown for the selected SKU as the controlling measurement. Inch values may be nominal or rounded. For example, a pull marketed as 5 in may use 128 mm CTC.
How to Measure Existing Holes
1. Remove the existing pull.
2. Measure from the center of one hole to the center of the other.
3. Use a ruler or caliper marked in millimeters when possible.
4. Compare the result with the CTC listed for the selected product variant.
Common Nominal Sizes
Common listings include approximately 3 in / 76 mm CTC, 5 in / 128 mm CTC, and 6-1/4 in / 160 mm CTC. These inch labels are convenient nominal references; the listed millimeter CTC controls fit.
If the CTC Does Not Match
A different CTC normally requires new holes or a compatible backplate that safely covers the old holes. Do not drill until the hardware has been test-fitted and the door or drawer construction has been checked.
FAQ
- Why do some listings show both inches and millimeters?
- Millimeters are commonly used for manufacturing and mounting dimensions. Inch values help U.S. customers compare familiar nominal sizes.
- Can I measure from the outside edges of the pull?
- No. Overall length is different from CTC. Measure the mounting-hole centers.
