Ronstan RF41111 Series 40 All Purpose Block – Single Loop Top & Becket

Great all around solution

The Ronstan RF41111 Series 40 All Purpose Block – Single
Loop Top & Becket features a self-lubricating Acetal
polymer sheave running on polished stainless steel race to 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 to swivel as required. And, the
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.
