Scanstrut DS21B-P Small Deck Seal Grey

Scanstrut DS21B-P High-Impact Plastic Small Deck Seal – Grey (DS21B-P)

The Scanstrut DS21B-P is a marine-grade High-Impact UV-Stable Plastic Small Deck Seal finished in aesthetic grey, designed to pass small pre-terminated cables and marine connectors through decks, cabin roofs, and bulkheads without cutting or unsoldering factory plugs. Engineered to accommodate connectors up to ∅ 21 mm (0.83") and outer cable diameters between 9-14 mm (0.35"- 0.55"), it provides an IP68 100% waterproof seal around VHF, GPS, transducer, and solar panel cable runs.

Featuring a low-profile, domed profile molded from UV-stabilized grey glass-filled nylon, the DS21B-P utilizes a tapered split neoprene bung alongside a captive base gasket to eliminate the need for liquid silicone sealant during installation. The plastic housing delivers impact resistance, zero risk of metal corrosion, and long-term durability under harsh weather and saltwater exposure.
