90 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 (4 PACK)

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 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 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.

Good clamps

Use these all the time as a temp brace while doing test glue up arrangements. Also keeps my projects perfectly square while the glue is drying. them so much that I will be ordering a second set.

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.

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.

Really helpful with my dorm desk hutch project this weekend

Held all the items I needed at 90 degree angels so I could screw them in place and still stay plum. Also handy for gluing corners.

Good quality at a reasonable price.

Quality product that meets the need and expectation.

Very handy Priced well and good quality
