Measure my tube
TKO clamps are sized by the tube's OUTSIDE diameter — not the inside. Here's how to measure it in under a minute.
1 · Tube shape
2 · How are you measuring?
- Open the caliper jaws across the outside of the tube, square to the bar.
- Measure on bare tube — away from welds, tabs or bends.
- Take two readings 90° apart and use the larger one.
