Review on 🔒 Climax Metal C100BO Plating Collar by Austin Arvayo

These clamps worked great for my home gym, I used them as bushings for a leg extender. I like the black oxide more than the zinc as I typically use these collars where they need to be tungsten welded. Black oxide always grinds better, leaving a cleaner surface with less contamination (resulting in an unstable arc).
