All-purpose (AP) blocks are an excellent all-around solution. These blocks, designed for durability and long service life, are the right choice for sheets, halyards, and control line applications in cruising and racing. The self-lubricating Acetal polymer sheaves running on polished stainless steel races perform equally well with dynamic loads and high static loads.

The Captive Lock universal head can be fixed in either of two planes or free to swivel as required. This feature eliminates fouled lines and provides exceptional versatility. The blocks boast exceptionally high working loads and require low maintenance, ensuring a long service life.

The Series 40 All Purpose Block - Single - Universal Head is a versatile and reliable choice for a variety of maritime applications. Crafted with meticulous attention to detail, this block offers a range of features that make it an ideal solution for sailors and boat enthusiasts.

The UV-stabilized Acetal sheaves, combined with the impact and UV-resistant, fiber-reinforced Nylon cheeks, ensure the block's durability and longevity, even in the harshest marine environments.
