Housolution 90 Degree Right Angle Clamp - 2 Pack Aluminum Alloy Woodworking Corner Clamp with Adjustable Swing Jaw for Picture Frames, Cabinets, DIY Projects - Blue (Perfect for Woodworking, Metalworking & Home Improvement)

Product is fine but I ordered a two pack, received a single clamp instead of two. If you order a two pact, open immediately to see if you got one or two. The box for one is smaller but the two boxes are almost identical.These are perfect for getting my beehive boxes square… every time!Seem to be very sturdy. Easy to use. Work work nice.when tightening the shaft, wood 'twists' to the outside creating a small gap between the 2 wood pieces.moreover, one of the clamp's base is not flat, it's wobbly.for rough joins, this could work, but not for precise joins.NICE STURDY CLAMPSEs muy útil para pegar maderas en ángulos de 90°GreatNice design idea with an Achilles heel.The idea is pretty simple: a right angle clamp for holding joints square while you attach them. While you cant use it in every situation, it does reduce the need for using 3+ items to square a corner.The materials seem sturdy, with one major exception. Where the end of the threaded rod disappears into the jaw of the clamp, the rod is held in place by a tiny, thin clip. I have used the clamps on 8 joints as of this writing, and during two of those uses the clip has come off the rod inside the jaw.To fix this, you have to perform surgery on the jaw to put the clip back on. You have to snap a tiny clip onto the end of a very short piece of metal in a very small space. (If this happens to you, I had the most success using pliers to snap the clip into place after repositioning it.)I have spent more time fixing these clamps than time they have saved me by using them.There are many other companies who sell these kinds of clamps. I would choose ones made at a different factory with a different design. If you look at the pictures it's not hard to tell which ones are identical.Love these should have bought them years ago. Really helpful when aligning units .No problems or complaints- do what I bought them forExcellent items,mounted these on small table,works perfect.*****Really sturdy and adjustableSimply whatever you clamp up won't square
