In addition to the screw, each mounting location between the two clamps is keyed for a very tight fit that won't shift. We added on board storage for the hex wrench that allows the user to re configure the clamps.
I produced a Keyshot animation for the carousel images on the website to show how the clamp reconfigures.
Another inspiration for the size and look of these clamps was snowboard vises, these can also be used for edge tuning a snowboard or skis.

Hold-It Bench Clamps

This is a set of adaptable interlocking clamps that provide modular vise like work holding capabilities on a variety of benches. I first had the idea for these clamps when I was doing work on a door to install at my home. I didn't have a good way to hold it vertically and other than large permanently mounted vises there is not a good way to hold work pieces vertically. these consist of a clamp that mounts to a bench and another clamp that mounts to the workpiece. The bench clamp has a wide foot and the workpiece clamp has a unique angled quick release that allows it to be pushed closed. The workpiece clamp mounts to the bench clamp in various orientations depending on the operation and workpiece size. Like all other Rockler products in my portfolio, while I was the primary designer. These were developed in collaboration with a small team of designers and woodworkers who all help make these products a success.
