90-Degree Rectangular Handrail Base Mount (commonly classified as a Through-Hole Stanchion Base). It is a structural marine hardware fitting used to secure continuous safety rails flat against a boat deck or cabin wall.
Core Function & Features
Continuous Pass-Through Tunnel: Features a hollow cylinder body that allows a continuous piece of piping to slide completely through, making it an ideal intermediate center-support bracket.
Perpendicular 90° Standoff: Holds the handrail tube exactly parallel to the mounting surface at a sharp, straight angle.
Dual Set-Screw Fasteners: Equipped with two pre-drilled threaded holes along the crown spine to accept set screws, locking the rail sleeve into position so it cannot twist under heavy grip force.
Surface Mounting Flange: Engineered with a four-hole rectangular mounting plate designed for heavy-duty countersunk deck screws or through-bolts.
Material Construction: Cast from heavy-duty 316 Marine-Grade Stainless Steel and polished to a mirror shine to withstand relentless exposure to corrosive saltwater environments.
