Cleveco Stainless Steel Backing Plate – 6mm Mounting Holes

Strengthen your deck hardware installations with the Cleveco Stainless Steel Backing Plate – 6mm Holes—a durable, load-spreading solution designed for reliable performance in marine environments.

Constructed from marine-grade stainless steel, this backing plate offers excellent resistance to corrosion and wear, making it ideal for long-term use in saltwater conditions. The precision-drilled 6mm (1/4") mounting holes allow for easy alignment with standard marine fasteners, ensuring a secure and professional fit.

Designed to distribute loads across a wider surface area, this backing plate helps prevent stress damage, cracking, or pull-through on fibreglass, timber, and composite decks. It’s an essential upgrade for improving the strength and longevity of your boat’s fittings.

Slightly larger than the 5mm version, this model is ideal for heavier-duty applications where increased bolt size and holding power are required.
