Product Overview

Rigging Hardware Double-Ended Snap Hook – Stainless-Steel  / “Snap Hook for Diving” – Model ZB6204-DE Series
RICHWITS ZB6204-DE gives you two safe gates in one forging—perfect for BCD shoulder D-rings, stage-bottle rigging, scooter bridles or any place you need instant, tool-free connection at both ends.
Precision-investment-cast from 316 marine stainless, then mirror-polished and electropolished for lifetime immunity to salt-spray, chlorine and tropical humidity.
Symmetric double-round eyes swivel 360° independently; each spring gate closes with 4 kgf preload yet opens under 12 kgf pull—glove-friendly even underwater.
Five lengths (65–115 mm) cover working-load limits from 30 kgf to 110 kgf—ideal for scuba, technical diving, hammock suspension or dual-anchor bridles.

FAQ

Q1: Will 316 SS really never rust in seawater?
A1: Correct—2-3 % Mo gives lifetime immunity to chlorides; rinse with fresh water after each dive to keep the mirror shine.

Q2: What safe working load (SWL) per double hook?
A2: From 30 kgf (65 mm) to 110 kgf (115 mm); divide total load by number of hooks—safety factor 4:1.

Q3: Can I use the 90 mm or 100 mm for hammock suspension?
A3: Yes—100 mm rated 90 kgf; typical 100 kg hammock needs 2 pcs for 4:1 safety.

Q4: Will the gates open under vibration or rolling?
A4: No—spring preload 4 kgf; tested 24 h vibration 50–500 Hz, zero accidental release.

Q5: Are spare springs or PVC sleeves available?
A5: Yes—stainless spring kits and coloured sleeves, MOQ 50 pcs, $0.10 each.

Q6: Do you offer test certificates?
A6: Mill certificate for 316 SS, salt-spray report, and proof-load certificate supplied free on request.
