Product Introduction
Anti-Rust: Marine-grade 316 stainless steel, molybdenum-alloyed for ultimate salt-water immunity.
Heavy-Duty: One-piece precision casting, 5 mm wall thickness—handles high line loads and impact.
30° Pre-Set Angle: Ideal for safety rails, hand-holds, bimini & canopy frames—fast, weld-free installation.
Wide Application: Perfect for ship rails, yacht push-pits, cabin-top handrails, T-tops, bow rails, swim platforms.
Mirror Polish: 400-grit finish (Ra ≤ 0.4 µm) for yacht-grade aesthetics and easy rinse-down.
Silent Grip: Nylon liner option eliminates stainless-on-stainless squeak.

FAQ
Q: Can I weld these bases instead of bolting?
A: Yes—316 cast is low-carbon for excellent weldability; use 316L rod and pickling paste after.
Q: Will the 30° angle work for 25°-35° rail slopes?
A: The 4×6 mm holes allow ±4° rotational adjustment; outside this range select our adjustable 0–45° version.
Q: Do I need isolating pads for aluminium decks?
A: Always use PTFE or Delrin isolators to stop galvanic corrosion between 316 SS and 5083/6061 Al.
Q: How do I clean mirror polish after season?
A: Rinse with fresh water, wipe with micro-fibre and vinegar solution; follow stainless grain to avoid swirl marks.
Q: Are these bases compatible with 1" Schedule 40 pipe?
A: 25 mm ID variant fits 1" OD (25.4 mm) tube—light interference, use Loctite 638 for permanent bond.
