cable chain no support

A cable chain that doesn't need support. They are in 19mm, 30mm, 39mm and are made to fit on 20+ aluminium extrusion There is 2 variants, smooth that are easy to put together and lower sound and friction, strong that works great for long chains or with low curve height.You can combine them to get smooth and not to much drop on height. the lowest turn height are around 58mm and the angle between parts are 50.The locks have rounded ends so you can have them open on one side but still attached. I made this for my diy cnc and laser machines.
