Description

The Ronstan Series 40 Single All Purpose Block is a great all around solution. A self-lubricating Acetal polymer sheave running on polished stainless steel races performs equally well with dynamic loads and high static loads. For durability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.

Captive Lock™ universal head can be fixed in either of two planes, or free to swivel as required. Becket pin is removeable so line can be spliced prior to fitting and is ingeniously locked into position without the use of a clevis pin, split ring or tools.
