It's great to have different colors to signal different cables. I just fasten them to the one side of the cable to keep it attached at all times. Then when I wrap my cables up, I just wrap the tie around the coil.
These are great cable ties, we purchase these cable ties for two reasons. One is the price, how can you not purchase these ties at such a great price for 100 pieces and second is the length because we were tie a big group of CAT6 together and it need to be able to easily remove in case we need to adjust. Great product.
