Ronstan Sailing Hardware
Series 40 All Purpose Blocks

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.Captive Lock™ universal head can be fixed in either of two planes, or free to swivel as required. Quick adjusting cleat arms require no tools to adjust and fix securely in position. Becket pins are removeable so lines can be spliced prior to fitting and are locked into position without use of split rings or tools.

RF41151's and RF41811's may be double stacked but the upper sheave should be subjected to no more than 60% of M.W.L.
