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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Costco Trinity shelves *by T***P on July 25, 2025* Works with 1" diameter Costco Trinity shelves.
