Description
Ronstan Series 40 Double Becket Block – RF41210 – 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.
Head can be locked at 0° or 90° by removing the shackle and changing the headpost orientation.
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.
