Scanstrut DS21B-S Black Stainless Deck Seal 9-14mm

Scanstrut Small Deck Seal - Black Stainless Steel (DS21B-S)

The Scanstrut DS21B-S is a premium, high-durability Small Cable Deck Seal featuring a Black Stainless Steel top cover designed to provide IP68 100% waterproof cable routing through marine decks, transoms, and cabin bulkheads. Built to accommodate pre-fitted cable connectors up to ∅ 21 mm (0.83") and cable diameters ranging from 9 mm to 14 mm (0.35" to 0.55"), it eliminates the need to cut factory connectors off valuable marine electronics cables during installation.

Constructed with a marine-grade 316 stainless steel outer shell treated with a durable black finish and a high-impact base plate, the DS21B-S utilizes a split-seal rubber bung system. The tapered neoprene bung compresses tightly around the cable when tightened, preventing water ingress under severe washdown conditions while protecting cables from chafing and structural wear.
