Tip: Measure your pole’s hole—if it’s around 23 mm and uses coarse threads, you’re good!
Please Test Whether Your Pole And Old Connector Size Meet The Parameters
“Threads Won’t Engage?”
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.
Connector Feels Loose?
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.
