Features

Overview: The Scanstrut DS21B-S can provide a water-tight seal for vertical cable runs in your boat or watercraft. The DS21B-S includes a tapered dome-shaped shell, made of stainless steel, and 4 rubber bungs - 3 with pre-drilled holes, and one solid that can be drilled to size. Each rubber bung is tapered to provide an IP68 watertight seal when the shell is tightened down over it.

Cable Seals: Four rubber bungs are provided for sealing the cable entry; one solid bung, that can be drilled to the required wire size, and three additional bungs that have been pre-drilled for: 0.35"-0.39", 0.43"-0.47", and 0.51"-0.55". The pre-drilled bungs are split down one side, letting you fit them around a cable without having to fit the cable connector through. The DS21B-S can accommodate wire ranging from 0.35" - 0.55" in diameter.

Styles: The DS21B-S features a stainless steel outer shell. Additional available styles include black impact-resistant plastic (sold separately).
