Anti-Rust & Salt-Water Ready
Marine-grade precision-cast 316 stainless steel, molybdenum-enhanced for life-long immunity to salt-spray, brine and coastal humidity.
Heavy-Duty Backbone
4.5 mm solid cast body—thicker than market average—handles high cantilever loads without flex or fatigue.
45° Quick-Fit Geometry
Rectangular foot with pre-set 45° corner angle eliminates on-board mitring; drop-in replacement for 7/8" (22 mm) & 1" (25 mm) rails.
Silent & Safe
90° inside corner keeps rail clear of walking surfaces; no tripping, no rattling, no metal-on-metal squeal.
Versatile Mounting
Four Ø5 mm countersunk holes give 360° fastening options on decks, cabin tops, toe-rails, pulpits, T-tops and radar arches.


| Advantage | 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. |
| Application | Function | Marine Value |
|---|---|---|
| Push-Pit / Pull-Pit Rails | 45° corner support for life-line terminations | Maintains rail height & tension under ISO 15085 |
| T-Top & Bimini Frames | Corner brace for overhead structures | Survives green-water impact & 100 km/h wind gusts |
| Radar Arch Supports | Diagonal strut footing | Zero corrosion staining on white gel-coat |
| Bow Rail Wing Extensions | Retrofit anchor-roller wings | |
| Deck Stanchion Bases | Retrofit repair base for cracked weldments | Faster turnaround than full rail replacement |
| Cabin-Top Hand-Hold Rails | Corner anchor for safety rails | Sure grip even when drenched in spray |
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.
