Maxwell Chain Stoppers 8–13 mm (Height Matched & Levered) — Parts List

Why a Chain Stopper

Windlasses are not designed to hold the high loads that can be transmitted through the chain at anchor: secure the chain with a chain stopper, or the rope to a cleat, bollard or other load bearing point.

  • Height matched to the chain level of the RC series windlasses – no packers or plinths needed.
  • Body and pin in 316 stainless steel; pawl in high strength 2205 stainless steel; mirror polished finish.
  • Takes the weight off the windlass and prevents accidental free fall of the anchor while under way.
  • Safe working load greater than the chains it is designed for (DIN766, G30 & G43).
  • Pawl shaped to match the chain, so it does not damage the galvanising the way a traditional pawl does.
Code Chain Windlass (product information sheet)
P104358 8–10mm (5/16–3/8") RC8
P104359 10–13mm (3/8–1/2") RC10 & RC12

The table on page 2 of the same sheet labels P104358 "to suit RC10" and P104359 "to suit RC12" (as printed); page 1 gives RC8 and RC10 & RC12 as above.
