I had a live edge sign I laser engraved that had a curled edge. I needed a way to drill eye hooks into it and this was my idea. It slides against the flattest edge and the other side allows it to clamp around the curl. It's easily modified to what you are working with. I have 2 versions. One is just a squared version and simple. The other is a little more rounded and "futuristic" LOL. Hope this helps someone
