Gloma Nautica Long Captive‑Pin “D” Shackles – Forged AISI 316 Stainless Steel

Gloma Nautica’s Long Captive‑Pin “D” Shackles combine expert craftsmanship with thoughtful design, delivering exceptional durability and user safety for critical rigging tasks. Entirely forged in Spain from AISI 316 stainless steel, these shackles feature a durable body and a pin that remains securely in place—eliminating the risk of loss during installation or operation

Key Advantages & Features:

• Marine-Grade Forged Construction
  Made from premium AISI 316 stainless steel and forged using both cold- and hot-forging methods, these shackles boast superior corrosion resistance and mechanical strength—far outpacing standard cast alternatives

• Extended Geometry (“Long D”)
  The elongated body provides increased clearance and flexibility for attaching lines or hardware without binding. This makes them ideal for rigging setups that require additional reach or accommodate bulkier fittings toplicht.com+3nautos-usa.com+3ebay.com+3.

• Non‑Removable Captive Screw-Eye Pin
  The captive design ensures the pin never detaches from the shackle—minimizing lost components and downtime. The integrated screw‑eye allows easy manual operation and prevents vibration‑induced loosening

• Certified Performance Ratings
  Sizes range from 4 mm (5/32″) to 10 mm (3/8″) with documented Working Load Limits (WLL) and breaking loads certified by independent labs like APPLUS:

  Pin Ø	Inside Width	Inside Length	WLL (kg)	Break Load (kg)
  4 mm (5/32″)	8 mm	30 mm	400 kg	1,000 kg
  5 mm (3/16″)	10 mm	38 mm	600 kg	1,500 kg
  6 mm (1/4″)	12 mm	45 mm	900 kg	1,800 kg
  8 mm (5/16″)	16 mm	58 mm	1,700 kg	4,300 kg
  10 mm (3/8″)	20 mm	70 mm	2,500 kg	5,700 kg

   

  • Polished Finish & Easy Inspection
    Each shackle is polished to resist wear and corrosion, and the clean finish aids quick visual inspections for deformation or wear.

  • Reliable Quality & Warranty
    Gloma Nautica’s products are tested by APPLUS in Barcelona for compliance with break-load standards. Shackles also come with a 5-year warranty, underscoring the brand’s confidence in long-term performance nautos-usa.com+13nautos-usa.com+13glomanautica.com+13.

  Common Applications
  Ideal for rigging requiring straight-line loads with added length—such as long-loop halyards, spinnaker cars, blocks, lifeline terminations, pulley systems, and industrial lifting tasks where alignment is essential.

  • Enhanced Reach: Longer body provides extra space while maintaining load capacity.

  • Corrosion-Resistant: AISI 316 stainless steel built for harsh marine conditions.

  • Captive Pin Safety: Screw-eye pin ensures secure connection and tool-free installation.

  • Certified Strength: Clear WLL and breaking load specs for safe rigging.

  • Forged Reliability: Grain-aligned metallurgy offers fatigue-resistant performance.

  • Crafted & Certified in Spain: In-house forging, APPLUS testing, and a 5-year warranty glomanautica.com+12
