CUT TO SIZE service:
PTFE coaxial cables are not easy to cut. Luckily for you we now offer CUT TO SIZE service, we can cut the coax for you. All we need is exact dimensions. Cutting is done with professional equipment and the cable will look really well afterwards. There is no way to cut it so nicely without the special tool. See the video below. To order this service contact us for a quote or place order and specify measurements under details and we’ll get back to you with a quote. It is not expensive so it is very much worth the cost..

This is how this is done:
