Stainless Steel Capped Composite Thru-Hulls

Designed for the value conscious customer, these fittings provide the look of a stainless steel thru-hull at a fraction of the cost

Corrosion Resistance
Manufactured with high quality stainless steel caps and engineered composite bodies, these thru-hulls are designed to resist degradation as a result of chemical and saltwater exposure.

Consistent Look
To create a uniform look, Attwood has designed its 5/8" thru 11/4" barbed thru hulls with a common exterior surface.

Improved Installation
Always keeping the builder in mind, each fitting incorporates several different types of assembly features that allow for "single operator" installation.

Caution: Thru-Hull connectors are designed for installation above the water line only.
