Infinity Tools PRO-Grip バック・トゥ・バックアダプターキット

These adapter plates lock onto my clamp bars perfectly without any wobble, and the machining is precise enough to keep my glue-ups square every time. I’ve already used them for a cabinet carcass and a small bookshelf—definitely a game-changer for parallel clamping.

I was skeptical about how well these would hold up, but they snapped onto my straight edge clamps in seconds and haven't budged. The interlocking design is solid, making it easy to clamp tight joints across long panels.

The adapter kit locks into my PRO-Grip clamps without any wobble, so I can finally clamp both sides of a panel in one setup. It took me under a minute to swap the pieces around, and the whole thing feels solid enough for heavy glue-ups.
