Routing cables through a bulkhead or deck should be clean, watertight and simple. The Scanstrut Horizontal Cable Seal delivers on all three.
Designed for solar panels, light bars, deck lights and rooftop electronics, it provides a guaranteed watertight seal with no messy sealant and no complicated installation. Available in two sizes covering cable diameters from 2mm to 10mm.
Design
Both models feature a low-profile dome shape that sits neatly against the surface for a clean, professional finish. Impact-resistant construction adds extra protection against water ingress.
The DS-H6 is Scanstrut's most compact horizontal seal. The DS-H10 is their most popular — available in grey or black with a self-drill bung option for maximum flexibility.
Marine Grade Materials
Built from UV-stable, hard-wearing high-impact plastic for long-term performance in sun, salt and spray. Both carry a full IP68 rating for a guaranteed 100% watertight seal.
Easy Installation
Captive nuts are built into the base of both models. No loose fixings, no sealant on the bungs, no fuss. Fast to fit first time and just as reliable on repeat installations.
