White Indoor & Outdoor Single Cable Hole Cover KitKit Contents:1x White Brick Buster Plate1x 8mm Single Cable Feed Through Wall CapOverview - The feed through bushing is designed to cover damaged brickwork, plasterboard, wood or other materials where a cable enters or exits the interior of a building, and the brick buster plate is designed for the same reason but for external use. They can both be glued into position with silicone sealant easily. The bushing and brick buster helps protect the cable from damage and when installed with silicone will help prevent the ingress of water into the hole in the brickwork. If the feed through wall cap is installed into plaster board, sealant isn’t always necessary… It can simply be inserting into the wall and the grips should hold it (add sealant if you need to).Technical Specification (Brick Buster):10cm x 10cm Made from quality Plastic Technical Specification (Feed Through Wall Cap): Round Cap: 31mm (diameter)Depth: The bushing is 27mm deepMax Cable Diameter – The thickest cable this grommet will accept is 8mmCut-out – A cut out of 10mm is required for this bushingThis kit can be purchased in either black or white and in a single or twin/shotgun cable feed through wall cap (please search our shop for more details).
