The maximum size of a single cable must not exceed a diameter of 5.5mm.
10mm clips can be used for cables whose measurement does not exceed the size of the cross-section mentioned above.
The flat cable clips can hold two wires of this size by placing them next to each other.
For Example Coaxial Cable type:
3C-2V - 5.4mm; which is commonly used for domestic TV signals is ideal for 10mm clips.
The same sizes are
RG-223 / U and H155.
With a slightly smaller cross-sectional area are these types
1.RG-400 / U,
2.RG-142 / U,
3.LMR-195,
4.LMR-200,
5.HDF-200,
6.CFD-200 - 4.95 mm.
