Clamp can be used for the inner triangle and reversed to clamp the outer triangle. I ordered him to fix the dresser; I had to glue the pieces together after they broke and at first I used two regular clips to hold the corners together. It was painful because I had a lot of corners for multiple drawers. With the corner clip I just use one clip to hold the corners together and wait for the glue to dry. The clamp worked fine. It was easy to use; It made my job easier because I used fewer clamps and the process was faster. I like the simplicity of the design. I'm not a carpenter, my job was easy but required the right tools.
