Stainless capped resin straight thru hull 1 1/8 & 1 1/4" XL

Product Description

Upgrade your boat’s thru hull fittings with our Premium Straight Thru Hull Fitting, engineered to deliver outstanding durability, performance, and style without the weight and cost of full stainless steel construction. Trusted by leading saltwater boat builders, this fitting offers reliable, long-lasting service in harsh marine environments.

Constructed from tough fiberglass reinforced resin, the fitting provides excellent resistance to saltwater corrosion, UV rays, and wear. The polished 304 stainless steel cap, ultrasonically welded to the outer flange, not only enhances your boat’s aesthetics but also offers superior protection against sun and salt damage, eliminating common issues with conventional plastic thru hulls.

Its extra-long threads support installation in transoms up to 3-7/16" thick, providing versatile mounting options for different hull thicknesses. The included mounting nut simplifies installation, making it quick and secure.

Ideal for saltwater boats, sailboats, fishing vessels, and yachts, this thru hull fitting is the smart choice for boat owners seeking strength, reliability, and a refined finish.
