Completed cable rail project

"Hi Kristi and others. Well I completed my deck expansion and cable railing project. It was a challenge as I hadn’t done this before but with your help and others there at Cable Bullet it really went quite smoothly. With the one exception of the wire cutter furnished in the kit everything was very good quality. The crimper was especially excellent. I’ve attached a photo of the completed project and once again want to thank you and all those at Cable Bullet. Everyone that sees our deck and cable railing really like it. I can assure you that we are the only one of 2200 spaces in this RV park that have cable railing. Thanks again."
