Ronstan's Series 50mm 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. They have a fixed, grade 316 stainless steel load strap/loop top. The becket pin is removable 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.
