Boat owners, this SeaLux stainless steel grab rail is exactly what you need for added safety and support on your vessel! Made from polished 304 grade stainless steel that can handle the harsh marine environment without rusting or corroding. The elliptical tubing shape (1\ x 3/4\) feels comfortable in your hand and looks sleek on your boat. You can choose from several center-to-center measurements: 9\, 12\, 16\, or 18\ to fit your specific space needs. The rounded 45-degree radii take up less space than standard 90-degree corners, which is great for tighter areas on boats. The overall length is about 13 1/4\ for the 12\ model, with a comfortable 1 1/2\ clearance between the rail and mounting surface. Each rail comes with two 5/16\ diameter threaded mounting holes that are 1 3/4\ long for secure installation. Just a heads up - the mounting studs aren't included since different installations require different hardware depending on your hull thickness and material. These grab rails are perfect for providing support near boarding areas, in cabins, on fly bridges, or anywhere passengers might need extra stability while moving around. The polished finish looks professional and maintains that classic marine appearance. Installation is straightforward for anyone with basic DIY skills. This is one of those marine accessories that adds both safety and value to your boat!
