Scanstrut DS40-S Vertical Cable Seal - Stainless Steel

The Scanstrut DS40-S Vertical Cable Seal in stainless steel is an essential penetration solution for marine-grade electrical installations and automotive wiring harness management. Whether you're running custom gauge wiring through bulkheads, engine bays, or sealed enclosures, this cable seal prevents water ingress, corrosion, and environmental contamination at the point where cables pass through structural barriers. Mechanics and fabricators rely on this product to maintain watertight integrity in high-moisture environments where standard rubber grommets or open pass-throughs would compromise system reliability.

Constructed from marine-grade stainless steel, the DS40-S delivers superior corrosion resistance compared to aluminum or powder-coated alternatives—critical in salt-spray environments or where persistent moisture exposure accelerates oxidation. The vertical cable seal design accommodates multiple cable diameters within a single compact footprint, allowing flexible bundling of mixed gauge wires without stress concentration or pinching that could compromise insulation or signal integrity. Its threaded mount pattern facilitates secure installation into bulkhead fittings, deck plates, or custom fabricated enclosures with minimal vibration-induced loosening or micro-movement that degrades sealing performance over time.

This seal is ideal for custom vehicle builds, marine electronics retrofits, auxiliary lighting systems, winch installations, and any application requiring sealed cable passage through structural barriers. Off-road and expedition-build communities frequently specify stainless steel cable management to eliminate repeated maintenance cycles and extend service intervals in harsh terrain. Installation requires a standard bulkhead fitting compatible with the DS40-S mounting thread—consult your vehicle's wiring diagram or enclosure specifications to confirm thread pitch and bore diameter before ordering.
