Precision 90° Aluminum Corner Clamp - CNC Woodworking Positioning Square for Cabinets & Frames
Building Cabinets Alone Shouldn't Feel Like Climbing Mount Everest.
Meet your ultimate "Third Hand" for flawless 90° joints.
🛑 Stop Fighting the "Glue Shift"
We've all been there: you square up your boards, apply the glue, and right as you tighten the clamps... the corner shifts and ruins the box. These precision aluminum corner clamps stop that instantly.
Why Woodworkers Are Trashing Their Old Clamps:
-
📐 True 90° Dead-Square Lock:
5-axis CNC machined from heavy-duty aluminum to a razor-thin tolerance. Once it's clamped, that angle is locked dead square before any pressure goes on. -
🛠️ Unmatched Versatility (Not Just Corners):
Works perfectly for inside corners, outside corners, and T-joints. Ideal for building partitions, drawers, frames, and complex shelving units solo. -
📏 Built-In Precision Measurements:
Features highly visible, laser-etched Imperial & Metric rulers directly on the sides, turning your clamp into a precise layout tool. -
⏱️ Set It & Forget It:
The 5.15-inch extended screws handle wood from 0.4" to 3.5" thick. Lock it in seconds and free up your hands to drive screws or use your brad nailer.

No more gaps in my picture frames!
I’ve always struggled with those tiny, annoying gaps at the corners of my frames. These positioning squares are a total game-changer. They hold the 45-degree cuts perfectly at a right angle while the glue sets. My frames actually look store-bought now. If you're into framing, don't hesitate.

Batch building drawers just got faster.
I had 12 drawers to build for a workshop cabinet. These clamps saved me hours. They are heavy-duty enough to square up 3/4" plywood without any flexing. The knobs are easy to turn even with gloves on. Much better than the plastic versions I used before.

Spot On 90° - Verified!
I checked them against my Woodpeckers square as soon as they arrived, and they are spot on 90 degrees. No burrs on the edges, and the anodized finish is smooth so it won't mar the wood. The clamps are strong enough to hold heavy plywood without slipping. Highly recommend for any serious woodworker.

Total Life Saver!
Man, I wish I’d grabbed these sooner. I used to fight with cabinet corners all day, trying to keep 'em straight while driving screws – total pain in the neck. These blocks are like having a buddy hold the wood for ya. Solid metal, real tough, and dead-on 90 degrees. My new kitchen cabinets actually look straight for once. If you’re working solo, just get 'em.

Saved my husband's sanity!
Bought these for my husband because I was tired of hearing him swear in the garage every time he tried to build a drawer. He's been using them all weekend to build a new table saw stand and hasn't complained once. He even bragged about how 'perfectly square' the base is now. Best gift I've bought him in a while!

Best DIY investment ever!
I built this entryway console table all by myself! I was so worried about the corners being crooked, but grabbing the 4-pack set made it easy. They acted like a second set of hands for the frame and drawer openings. It’s perfectly level and looks professional. If you're tackling furniture projects alone, get the 4-pack—you’ll need one for every corner!
