White Plastic Vertical Cable Seal for Wire Up to 13.5mm/0.53"The Seaview Cable Seals (also known as CableClams, Cable Glands, or Deck Seals) provide waterproof cable routing. These are made of very strong plastic or marine grade 316 stainless steel and come in a variety of colors and finishes. Seaview cable seals fit a wide range of cables and connectors. Seaview Cable Seal options for 17mm to 34mm (0.67” to 1.38”) connectors, making it ideal for almost every installation.Features:No need to remove connectors - The split seal design eliminates the need to remove cable connectors during installation.  Watertight installation - Tapered rubber seal forms watertight installation. The base gasket is also provided for a clean, watertight installation. Waterproof rating of IPX6 and IPX7Improved shape and design - Low profile design for a strong, impact-resistant, and clean installation. No sharp edges Drill tubes included - Each cable seal comes with 4 brass drill tubes (6, 8, 10 & 12mm). These are used to drill very clean and easy holes vs a typical drill bit. Some other brands do come with pre-drilled rubbers but we choose to include metal drill tubes that can be recycled or reused when finished vs the extra rubber pieces that will end up in the landfill from others Note:*All Seaview Cable Seals (including the round Cable Seals) will work with more than one cable as long as each cable has its own hole and there is at least .125" of rubber around each hole.
