This model is customisable. Adjust the od/id diameter parameters should be enough in most cases.

How to use

Measure the wall hole and diameter of the cable. You may add a little tolerance like 0.2 mm

Click the ‘Customise’ button and input your measurement to make your desired size. Isnt it easy?
