Heavy rigging, longer spans, or a load that's pushing past 300kg? The 4mm and 5mm won't cut it. This Ronstan 6mm bow shackle handles 520kg max working load in forged 316 stainless steel. Same standard-head profile, same wider bow opening for threading multiple lines or wire. It's the biggest in this Ronstan set, and it's the one you reach for when the job says 'don't let go.' No rust, no drama, just a solid connection that holds
