All-purpose block series 50 - single - becket - universal head

All-purpose blocks (AP) are an excellent multi-purpose solution. Self-lubricating acetal polymer sheaves running on polished stainless steel raceways perform well with both dynamic and high static loads. For their durability and long life, these blocks are the right choice for sheeting, halyards and control line applications for cruising and racing. The Captive Lock universal head can be fixed in one of two planes, or free to pivot as needed. The clevis pin is removable so the line can be spliced before rigging and is ingeniously locked into position without the use of a clevis pin, split ring or tools
