Some cable management clamps I made for a project
Sizes are in decimal inches (As you can stick fractions in a file name)
I also have metric models as well that may be worth a look so that you can get the best fit, as you may have ¾" cable, but a 18mm clamp may give the best fit, as ¾" is 19.05mm)
The author marked this model as their own original creation.
