Ronstan RF41151 Series 40 All Purpose Block Single Cheek

Great all around solution

The Ronstan RF41151 Series 40 All Purpose Block Single
Cheek 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. Can
be mounted on masts and booms using the curved surface adapter. Can
be stacked to create a double version, but no more than 60% of the
rated working load should be applied to the upper sheave.
