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 triple-axis head can be locked in-line or perpendicular to the sheave by removing the shackle and changing the headpost orientation. It can also swivel freely.
Spare parts for this block include RF150, a 3/16 in. pin diameter, standard Dee shackle with a slotted pin. Related items include a snap shackle head adapter and a trunnion snap shackle head adapter.
