I have these for some of the work I do and it would be really handy to have an angle clamp. Top quality, no instructions. What I have in the package: 4 x CHGLMPOSS 90 Degree Rectangular Clamps 8 x Eyelets This product CHGLMPOSS 4 PCS 90 Degree Rectangular Clamp is made of corrugated and durable material, and the spring is stainless steel. Each polygon clip measures approximately 3.15" x 3.35" and is very lightweight. The floating jaw is spring loaded and you can work with materials up to 1 inch thick. I could not find warranty information in either the product information or the product description. There were no instructions so you'll have to figure out how to assemble the clamps disassembled in the box they came in. Not everyone is familiar with how they connect. information or product descriptions. I appreciate you taking the time to read this. I received this product in exchange for an honest review. Overall this is an average set of clamps. They're not high quality, but they work. I actually need something that will work with thicker wood, so I don't expect to be using them that often. Due to a lack of item information, it was impossible to tell how much space you would have between the moving jaw and the end of the clamp. It would be great for small jobs but I don't expect them to last that long. I hope this information was helpful. This product is made in China.
