Coastal-Grade Corrosion Shield Precision-investment cast 316 marine stainless, molybdenum fortified for lifetime immunity to salt-spray, brine and tropical humidity.
Rock-Solid Core 5 mm one-piece cast body—30 % thicker than DIN-standard bases—absorbs high cantilever loads without flex, fatigue or micro-cracking.
30° Quick-Fit Geometry Round foot with pre-cast 30° sweep eliminates on-board bending; drop-in replacement for 7/8" (22 mm) & 1" (25 mm) rails—no template, no mitre.
Silent & Safe Closed-ring design locks rail away from deck traffic; no rattles, no squeal, no snagged sheets or bare feet.
360° Fastening Freedom Four Ø 5 mm countersunk holes on a 360° bolt circle let you rotate the base to any clocking angle—perfect for curved toe-rails, T-tops and radar arches.
⚙️ Technical Parameters

Description
Salt & Brine Immunity
316 Mo-content resists pitting/crevice attack in continuous saltwater immersion.
One-Piece Casting
Zero weld seams = zero weak points; keeps shape after years of dynamic loading.
Mirror Polish
Self-cleaning surface, wipes free of deck grime; maintains yacht-grade aesthetics.
CNC Critical Faces
Rail bore ±0.1 mm for slip-fit assembly—no rattling, no adhesive shim needed.
Hidden Fastening
Countersunk screws sit flush, saving snags on sheets, shoes or bare feet.
Multi-Rail Compatible
Identical footprint accepts both 22 mm & 25 mm rails—reduce spare inventory.
FAQ
Q1: Can I weld this base after installation? A: Yes—316L composition allows TIG field welding; polish heat tint with included restore pad.
Q2: Do I need isolating washers for dissimilar metals? A: Not for 316-to-316 joints; use PTFE tape when bolting to aluminium to stop galvanic attack.
Q3: Is the quoted SWL per base or per pair? A: Per single base; always divide rail load by number of supports.
Q4: Will the 22 mm version accept 25 mm rail with a shim? A: We recommend ordering the correct size; wall thickness is optimised for slip-fit strength.
Q5: How do I maintain the mirror finish? A: Rinse with fresh water after each voyage; periodic wipe with pH-neutral stainless polish keeps the yacht-club shine.
