BRCOVAN2 PCS, 1'' Ball Mount Base with Aluminum Alloy 4-Hole AMPS Square Plate, Compatible with RAM Mounts B Size 1 Inch Ball Double Socket Arm

I ordered these and thought the base was larger. My bad. I drilled and tapped the part and screwed it to the broken metal base from my last ball which had broken off. So far it works just fine, I used 1/4:20 SS bolts from the bottom, loctite and self locking nuts on top.Nicely made product.

Best 1” balls I’ve found. Compact base size and great ball.

This is an excellent upgrade from plastic mounts, holds fast on all my vehicles even offroad. Highly recommended.

Excelente.

Looks well made, really won't know till next winter.
