## Questions & Answers

**Q: “Threads Won’t Engage?”**
A: Measure your pole’s inner hole with a caliper. It must be ≈23.0 mm. Verify pole’s thread pitch is 1.25 mm by measuring 5 peaks (divide by 5). Clear any burrs or debris inside before re-tapping.

**Q: Connector Feels Loose?**
A: Check your pole’s inner hole—if >23.2 mm, it will be loose. Ensure pole wall is ≈1.2 mm. Measure connector OD; it should be 23.0 ± 0.1 mm. If < 22.8 mm, replace with correct size.

Works with 1" diameter Costco Trinity shelves. However, advise wearing protective gloves when assembling because there may be metal burrs still intact.
