HARDELL90 Degree Positioning Squares Right Angle Clamps 5.5" x 5.5"(14 x 14cm) Aluminum Alloy Woodworking Carpenter Corner Clamping Square Tool for Picture Frame Box Cabinets Drawers

High quality. Great value. I liked them so much i bought a second set so now i have four clamps!

Strong and simple to use. Do an excellent job keep the pieces square. I liked them so much that I bought a second set.

I've used these clamps a lot building shelves and fitting out my garage.If you're working with rough lumber, they're already perfect. Just buy these and don't worry about anything else I'm about to say.However, if you're working with finished lumber or higher-grade plywood, you'll want to be careful.These clamps do not pull straight. The way they are designed, the "foot" meets the wood at an angle and so will bite into the edge of the wood as you clamp down. This is especially noticeable if you're needing to pull bowed pieces straight to get those 90* corners.You can easily fix that by putting a piece of furniture felt on the "foot" of the clamps so the force is distributed more softly and the metal is kept away from the edge of the boards you're working on.Some people (like me) are fine doing that bit of tinkering with their clamps for the value. But if you want something that won't marr your furniture project and that you don't have to mess with, these budget clamps may to be for you.

These are great. Its like having 2 more hands to help hold wood together before fastening them. They seem well made and accurate. I am glad I didnt pay the over $200 price tag of the ones i was originally going to buy. Those might be better for daily or professional use but for the occasional use that I am going to use these for, they work for me.

I like these things! Bought the double set and glad I did. Getting square and flat corners that matched has always been a peeve. These are cheap enough that I had no qualms in grinding the outer 90° corner of the block off for clearence and clamped two pieces of already cut wood to it. Then I ran the joint into a bandsaw and hada perfect, and perrfectly matching, joint. Easy to use but make sure the pins are square to the block when tightning. They get the job done. Everyone, from newbie to expert should have a set in the toolbox!

I purchased these clamps to use when I am making frames for my art projects. They work great and hold the wood securely. Easy to get off and on too. I only wished I bought the smaller size because most of my frames are 9 x 12 and you can't use all four clamps at a time so you have to glue two corners then wait for them to dry and then glue the other two. But that was my mistake. Overall these are great for any woodworking project.

I bought these to supplement my two Woodpecker's clamping squares. These came in a nicer kit and are just as precise, just MUCH cheaper.

The product works as advertised once I modified them.The bent screw shaft that's to fit into the bracket hole has a tolerance issue. Some of the holes in the bracket had to be enlarged to accommodate the support shaft.
