4 Pcs Right Angle Clamp, 90 Degree Corner Clamps for Woodwork, Single Handle Aluminium Alloy Vice with Adjustable Swing Jaw, Woodworking Clamps for DIY Woodworking Welding

Not a big challenge here: they hold the corner at the proper right-angle and make woodwork assembly/gluing that much easier. Use two per corner if the wood is more than a few inches across - you'll need one front and back because the clamps are not especially deep. Still recommended.

great for the price

Work well. Very handy.

I was making a number of rectangular frames to go around some windows. After struggling a bit on the first one to make sure the corners were square, I bought a set of these. What a difference, it's impossible to get it wrong. Just put your pieces in and tighten up. Only slight downsize is, if your clamp is touching your worktop, you can only use your finger to tighten the clamp

These are a good idea in theory, but they only work well for PSE wood that are not much taller than the depth of the clamp. So if you are working with planed squared edged timber this is a four star product. But if you are working with slightly rounded edged timber or timber that’s much deeper than the vertical edge, then you might want to put one on the bottom and one on the top of every corner to keep the corners true. Also, always double check if the movable bit is wedged correctly or not… if you loosen it too much, it might not wedge back correctly if you don’t see where it is going (that’s probably just the design of these kinds of clamps not an issue with this particular brand).

For gluing up external corners made from 2x4, I couldn't be any more pleased. This seems to be their maximum capacity for size of material. Extremely easy to locate, tighten, and remove after the glue has gone off. For reference, the corners clamped in the image are 2m apart, and even though this is my first attempt at working with such large material, the resultant joints were askew by no more than a couple of mm, which is more to do with the wood not being straight than anything else. If I get completely carried away with the woodworking, and need more corner clamps, I'll buy more of these in a heartbeat.

They'll work on my project for squeezing out mastic joints, but for any heavy duty work I'm not sure how the cross section in the ally would hold up.

These are excellent clamps, versatile set of 4. Makes for easy assembly of units when gluing and screwing and squaring up is needed. When an extra pair of hands could be useful, then these are them, do not hesitate to purchase. I wish I would of bought them a while back, time saving and accurate clamp set.
