Description

The Series 40 All Purpose (AP) blocks are versatile solutions for various applications. They feature self-lubricating Acetal polymer sheaves that run on polished stainless steel races, performing well under both dynamic and high static loads. These blocks are ideal for sheets, halyards, and control line applications in both cruising and racing, offering durability and a long service life.

The Captive Lock™ universal head can be fixed in two planes or allowed to swivel as needed. The cleat arms can be quickly adjusted without tools and securely fixed in position.

Features include exceptionally high working loads, low maintenance, and a long service life. The self-lubricating sheave, Captive Lock™ universal head, and slotted pin shackle prevent fouled lines. The multi-position cleat arm adds to its versatility.

Applications include mainsheets, halyards, vangs, and spinnaker control lines on off-the-beach catamarans, one-design classes, and sportsboats up to 8m (26ft). It's also ideal for fine-tuning mainsheet tackles, cunninghams, backstays, and other control line purchase systems.
