The new AnchorRescue II is sold in kit form and accommodates chain sizes ranging from 1/4” to 3/8” (6mm - 10mm), whereas the original models fit a specific chain size. The new model’s retriever is made of polished stainless steel, is heavier and has fewer moving parts.
The AnchorRescue II utilizes a removable sleeve in the slider to accommodate smaller chain sizes. The system ships with the sleeve installed. To use the system with 3/8” chain, simply remove the 2 set screws and the sleeve as shown.
