Product Details
Everything you need to know — features, specs, fitment, and answers to the most common questions.
True 90 degrees, hands-free
Holds both workpieces locked at a right angle so you can drill, screw, or tack with both hands on the fastener.
Independent jaw screws
Clamp two different stock thicknesses in the same corner — face frame to panel, no shimming.
One-person assembly
Boxes, drawers, and frames go together square without a helper holding the far end.
Lifetime warranty — no receipt
Fails under normal use, we replace it. Simple as that.
- Can it clamp two boards of different thicknesses?
- Yes — each jaw tightens independently, so you can join 3/4-inch stock to 1/2-inch stock and both stay seated at 90 degrees.
- Is it covered if it breaks?
- Lifetime warranty. If it fails under normal use we replace it — no receipt, no questions.
- Shipping details?
- Orders placed before 2pm ET leave our Columbus, OH warehouse the same day. Free standard shipping over $49.

Cabinet boxes come out square every time
Assembled fourteen base cabinets on my last kitchen job using a pair of these. Hold the corner dead at 90 while you drive pocket screws and the box comes out square without fighting it. Saves a second set of hands.

Made my first picture frames actually square
Built six picture frames and a shadow box over a weekend. Clamped each corner, checked with a square out of habit, and every one was true. Way easier than band clamps for a beginner.

Works for light metal frames too
I tack-weld light square tubing frames and these hold corners fine for tacking. Just keep the spatter off the screw threads. For heavy plate you want a dedicated welding clamp, but for light frames it does the job.
