TACO Marine Stainless Steel Hollow Back Rub Rail, 3/4 in, Polished

Overview

The TACO Marine S11-4511 is a 3/4 inch stainless steel hollow back rub rail made for adding a polished metal guard over compatible rigid vinyl rub rail on a boat’s hull edge. Its concave back fits over the vinyl profile, helping protect high-contact areas from dock rub, fender movement, trailer contact, and everyday chafe while also giving the boat a clean stainless accent.

This rub rail is supplied in polished stainless steel and is drilled and countersunk for #8 screws on 6 inch centers, which helps keep installation spacing consistent along straight runs and gentle curves. The range includes 12 foot, 16 foot, and 20 foot lengths, with 304 stainless steel options and a 316 stainless steel option for buyers who want the higher corrosion resistance associated with 316 stainless in saltwater use.

Key features

• 3/4 inch wide hollow back stainless steel rub rail for use over compatible rigid vinyl rub rail profiles.
• Concave back helps the stainless section sit over the vinyl rail for added chafe protection and a polished perimeter finish.
• Drilled and countersunk for #8 screws on 6 inch centers, reducing layout work during installation.
• Available in 304 stainless steel and 316 stainless steel configurations to match different corrosion-resistance needs.
• Polished finish gives the rub rail a bright stainless look suited to exterior hull and deck-edge applications.
• Made in the USA and backed by a 5-year limited warranty.

Variants

This product is offered in multiple lengths and stainless steel types so the rail can be matched to the run length and the vessel’s exposure conditions.

The width, hollow back profile, polished finish, and #8 screw installation format remain consistent across the range. The main differences are length and stainless steel type.

• S11-4511P12: Length 12', Style 304 Stainless Steel Hollow Back Rub Rail, 3/4”W x 12’L. This length suits shorter rail sections, repairs, or areas where a full long run is not needed.
• S11-4511P16: Length 16', Style 304 Stainless Steel Hollow Back Rub Rail, 3/4”W x 16’L. This configuration gives more continuous coverage for longer straight runs while using 304 stainless steel.
• S11-4511P16B: Length 16', Style 316 Stainless Steel Hollow Back Rub Rail, 3/4”W x 16’L. The 316 stainless steel version is a practical match for boats that spend more time in saltwater or harsh exterior conditions.
• S11-4511P20: Length 20', Style 304 Stainless Steel Hollow Back Rub Rail, 3/4”W x 20’L. This is the longest listed 304 stainless steel option and helps reduce joints on longer rub rail runs.

Installation and fit

Before ordering, compare the existing vinyl rub rail profile with the 3/4 inch stainless hollow back shape and confirm that the mounting surface can accept #8 fasteners on 6 inch centers. This style is commonly used as an outer stainless overlay, so fit depends on the shape and condition of the vinyl rub rail beneath it.

For replacement work, remove damaged fasteners, clean the mounting area, and check for old sealant, cracks, or uneven spots that could keep the stainless section from sitting cleanly. On curved areas, careful alignment and even fastening help the rail follow the hull line without kinks or raised edges.

Use cases on board

This rub rail is a good match for boat owners, yards, and builders repairing worn perimeter trim or upgrading a vinyl rub rail with a stainless face. It is especially useful around docking contact zones, hull sides that see fender movement, and exterior edges where a polished stainless finish is preferred over exposed vinyl alone.

Maintenance and care

Rinse the rail with fresh water after saltwater use and clean it with products suitable for stainless steel. Periodic inspection of the fasteners and the rail ends helps catch movement, corrosion staining, or impact damage before it affects the surrounding rub rail system.
