TACO Marine S11-4690 Stainless Steel Hollow Back Rub Rail, 1-1/2 in, 12 ft, Type-304, Polished

Overview

The TACO Marine S11-4690P12 is a 1-1/2 inch stainless steel hollow back rub rail supplied in a 12 ft polished Type-304 stainless steel length. It is made for the exposed perimeter of a boat, where the rail helps protect the hull-to-deck edge from dock rub, pilings, trailer guides, and everyday contact around marinas.

This profile is drilled and countersunk for #10 screws on 6 inch centers, which makes layout and fastening more predictable during replacement work. The hollow back shape suits installations where the rail needs to sit over the boat edge or over a compatible backing profile, while the polished stainless finish gives the sheer line a clean factory-style look.

Key features

• 1-1/2 inch hollow back rub rail profile for hull-side edge protection and trim replacement.
• 12 ft length works well for repairs, section replacement, or matching existing stainless rub rail runs.
• Polished Type-304 stainless steel gives the rail a bright finish and helps it stand up to normal marine exposure.
• Pre-drilled and countersunk for #10 screws on 6 inch centers to simplify alignment during installation.
• Useful on powerboats and fishing boats where the rub rail area sees regular contact with docks, fenders, pilings, and trailer hardware.

Installation and fit

Before ordering, match the 1-1/2 inch profile, hollow back shape, length, and screw pattern against the rail already on the boat. Rub rail profiles can look similar from a distance, so checking the cross-section and screw spacing is important when replacing only part of an existing run.

Fasteners are normally selected to suit the hull material, backing structure, and the exposure level of the installation area. A dry fit before final fastening helps confirm the bend, joint placement, and alignment along the sheer line, especially around corners and transom transitions.

Use cases on board

This rub rail is a good match for boat owners, yards, and refit shops replacing a damaged stainless section or refreshing the perimeter trim on a vessel that already uses a compatible 1-1/2 inch hollow back profile. It is especially practical for boats that spend time at busy docks, on lifts, or on trailers where the rail area takes repeated contact.
