Description

The Ronstan Series 40 All Purpose Block, Double with Becket is a double sheave all purpose block with becket and swivel shackle head (non-locking). 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.

Becket pin is removable 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.
