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

These things are really handy if you are looking to create nice 90deg joints. The angle brackets have a very nice finish and the hardware thus far seems robust.

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 know they sell this tool set with the intention of clamping to form a 90 degree corner while making cabinet doors or picture frames, etc. I am using them with my new CNC machine. Since they have been predrilled I have used bolts with locking knobs with T track to form strong corners for placing my wood onto the spoiler board. Perfect repeatable placement of wood means I can operate the machine on many consecutive pieces without having to do alignment for each piece. They are so strong I can apply clamp pressure for a great hold down. Maybe they should include some t track bolts that work with the included knobs and supplement their use for this purpose into their marketing information. Great set of tools that are packaged, manufactured, and delivered in perfect condition. I am very happy with theses.

These work great for assembly

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 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.

The quality in is even better than it looks!

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.
