Ronstan's Series 40mm 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.
The low profile, stand-up block has a swivel head post to allow full articulation and rotation. We recommend 2x5mm (3/16 in.) fasteners.
