gubbo 0 Posted October 7, 2022 Hi, I am installing a domestic Swann DVR4 cctv system at my house. The extension cables are twin cable. For the life of me I have tried to establish the best size/sort of cable clips to attach to brickwork. Can anyone advise size and sort please. Bought some larger 0.65mm clips but they are too big. many thanks Share this post Link to post Share on other sites
