Product Information
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.
Captive Lock™ universal head can be fixed in either of two planes, or free to swivel as required. Quick adjusting cleat arms require no tools to adjust and fix securely in position.
