Tristar White Cable entry cover, Pack of 5

Before fitting a new external security light I needed to secure the cable going outside & to stop any water egress indoors.
These are perfect, remembering to check the cable diameter first, & to drill the correct sized hole. They come in packs of 5, both good & bad point. Next weekend I'm fitting a new aerial at my mums & will be using another one from the pack to secure that cable.
Before Easter I'm going to fit CCTV cameras there also & i've checked that I can use these again for that. I use these in conjunction with the external cable entry cover for extra protection.
