The insert is used to assemble standard RTA panels with dowels using one additional part – the Clamp Cam.
The Clamp Cam contains a small die cast lever which acts on the post, drawing it tight once captured by the insert.
NOTE: The Clamp Cam is not a part of the insert patent. There are many ways to mate with the insert, so a manufacturer is free to use it, or manufacture an alternate mating component.
