Irwin 平行夾爪夾具，4" 深度，夾持力 1,150 lbs.

Glued up four cabinet doors last weekend and these stayed dead square through the whole thing. The parallel jaws really do hold their alignment even when I crank them tight, which I couldn't say for my old F-style clamps. At 1,150 lbs of force they've got way more squeeze than I need for most panel

Bought these for a box build and the jaws actually stay parallel under full pressure, which kept my miters tight instead of creeping open. The 1,150 lbs of force is more than enough for hardwood panels.

Glue-ups for a small cabinet came out dead square because the jaws stay parallel even when I crank them down hard. The 1,150 lbs of force is plenty for 3/4" panels, and the handles haven't slipped once.
