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.

Triple block features 2-way head that can be fixed at 0 or 90 degrees.

Sheave diameter: 40mm (1-9/16"). See Technical Specs for more information.
