Product Introduction
Anti-Rust & Salt-Water Ready
Marine-grade 316 stainless steel, molybdenum-enhanced for lifelong immunity to salt-spray, brine and coastal humidity.
Heavy-Duty Backbone
One-piece precision casting, 5 mm minimum wall thickness—outperforms welded plate hooks that fail at the heat-affected zone.
17-46 mm Auto-Grip Range
Spring-loaded shrapnel (roll-torsion) design self-adjusts to rope, chain, wire or tube diameters 17-46 mm; no tools, no loose inserts.
Silent & Safe
Polished radiused edges eliminate line chafe; integrated spring silences metal-on-metal rattle under wave impact.
360° Fastening Freedom
Oversized 8 mm eyelet accepts shackles, carabiners or lashing straps; optional M10 threaded boss for deck or bulkhead mounting.

❓ FAQ
Q1: Can I use the hook for lifting personnel?
A: No. SWL is certified for cargo only; human lifting requires EN 13155-certified gear.
Q2: Will the spring rust inside?
A: Spring is 316 stainless, shot-peened and epoxy-sealed; rated for 1 000 h continuous salt-fog.
Q3: Can I lock the hook open?
A: Yes, rotate jaw 180° against spring and insert 4 mm split pin (included) for maintenance mode.
Q4: Is the SWL per single hook or per pair?
A: Per single hook; divide total load by number of attachment points.
Q5: How do I restore the mirror finish after heavy use?
A: Rinse with fresh water, wipe with pH-neutral stainless polish; use 800-grit Scotch-Brite for scratch removal.
