Small Stainless Steel Clamshell Cable Entry Cover

316 Stainless Steel Cable Entry Cover for Marine and RV Cable Management

Compact, Low-Profile Design for Clean Cable Routing

The Small Stainless Steel Clamshell Cable Entry Cover provides a robust and discreet solution for passing cables through bulkheads, decks, or walls in mobile and marine environments. Pressed from marine-grade 316 stainless steel, this cover resists corrosion in saltwater, coastal, and harsh weather conditions, ensuring long-term reliability where standard steel or plastic alternatives would degrade.

With a footprint of just 41 mm wide x 44 mm long x 12 mm high, the low-profile design minimises snagging and maintains the clean lines of your vehicle or vessel. The arched cable opening accommodates common cable diameters, making it suitable for solar, antenna, or electrical wiring in caravans, RVs, boats, and off-grid installations.

Engineered for Harsh Environments

Unlike generic cable entry covers that use lower-grade materials, this cover is manufactured from pressed 316 grade stainless steel. This alloy contains molybdenum, which significantly enhances resistance to pitting and crevice corrosion in chloride-rich environments. For installers and owners, this means reduced risk of rust staining, structural failure, or water ingress over time, even when exposed to salt spray or industrial pollutants.

The polished finish not only adds a professional appearance but also simplifies cleaning and inspection. Three pre-drilled mounting holes allow secure attachment to flat surfaces using standard fasteners (not included).

Watertight Cable Protection

While the clamshell design inherently shields cables from direct spray and debris, the cover can be bedded with a marine-grade sealant (such as silicone or polyurethane) during installation to achieve a watertight seal. This practice is recommended for through-deck or through-hull applications where moisture ingress could compromise electrical systems or interior finishes.

• 316 stainless steel construction for superior corrosion resistance in marine and coastal settings
• Compact dimensions (41 x 44 x 12 mm) suit tight spaces without sacrificing functionality
• Arched cable opening guides wires smoothly, reducing chafing and strain
• Three pre-drilled mounting holes enable quick, secure installation
• Polished finish blends with modern RV and boat aesthetics
• Compatible with sealants for watertight integrity when required

Versatile Applications

This cable entry cover is ideal for a range of low-voltage and communication cable routing tasks:

• Solar panel wiring on caravan roofs or motorhome walls
• Antenna or GPS cable entry on marine vessels
• Battery monitor or sensor leads in off-grid cabins
• Lighting or accessory circuits in 4WD canopies and trailers

By organising and protecting cables at penetration points, the cover helps prevent damage from UV exposure, abrasion, and accidental snags, extending the service life of your electrical installations.

Why Choose 316 Stainless Over Plastic or Lower-Grade Metals?

Plastic cable entry covers can become brittle under UV exposure and crack over time. Lower-grade stainless steels (such as 304) may show signs of tea staining or pitting in marine environments. The 316 grade used here offers a measurable improvement in longevity, reducing the need for replacement and the risk of water damage to connected equipment.

Installation Tips

For best results, position the cover over a pre-drilled cable hole, apply a continuous bead of marine sealant to the base, and secure with appropriate fasteners through the three mounting holes. Ensure cables have a gentle bend radius to avoid stress at the entry point.
