The ‘cam clamp’ is not only aesthetically pleasing, due to the materials used to make it and its simple mechanism, but it is an effective, functioning clamp. It is lightweight and easy to use, but has been largely replaced by cheap F Clamps.
In use, the sliding jaw moves up and down the bar / stem. Material being clamped is placed between the two jaws. The cam lever is ‘opened’, which pushes the split in the moving jaw against the material being clamped. The force applied to the cam, also creates friction with the metal bar / stem, ‘locking the moving jaw in position. When pressure is released by ‘closing’ the cam lever, friction between the moving jaw and the bar / stem is removed and moving jaw slides down the bar / stem.
It is worth noting that cam clamps are often homemade, as they are relatively simply mechanical devices.

When in use, friction is created between the bar / stem and the moving jaw. It is locked in position, until pressure is released by closing the cam lever.
