Secondly, the OD of the cable wires must couple with the connectors’ wire channel(24AWG – 0.95mm; 26AWG – 0.9mm; 28AWG – 0.75mm; 30AWG – 0.6mm; 32AWG – 0.55mm)

If need, you can also insert the cable into a RJ45 boot as following picture,the RJ45 boot will protect the plug clip when cables are pulled through bundles.
