Product Overview

Marine Hardware Fixed-Eye Snap Hooks – 304/316 Stainless-Steel Easy Snap Hook – Model ZB6207 Series
RICHWITS ZB6207 gives you a no-twist, salt-proof connection that works from key chains to guard-rails.
Precision-investment-cast in 304 or 316 marine stainless (user-selectable), then mirror-polished and passivated for lifetime immunity to salt spray, chlorine and daily humidity.
Fixed oval eye keeps strap or rope aligned; spring gate closes with 4 kgf preload yet opens with 10 kgf pull—glove-friendly even underwater.
Six compact sizes (0#–3# / 53–100 mm) cover working-load limits from 50 kgf to 150 kgf—perfect for key rings, BCD shoulder D-rings, small-boat fenders or hammock suspension.
