Ronstan's Series 40mm All Purpose (AP) blocks are a great all around solution. Self-lubricating Acetal polymer sheaves running on polished stainless steel races perform 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.
The Captive Lock universal head can be fixed in either of two planes, or free set free to swivel. It's always a good idea to have extra RF150's (3/16 in.) pin diameter standard Dee shackles with a slotted pin.
Block accessories include: snap shackle head adapter (RF6170) and trunnion snap shackle head adapter (RF6171).
