40mm Dynamic Single Block - A2040

The 40mm Single block is our go-to dinghy mainsheet block. Also ideal for dinghy jib and spinnaker sheeting systems as well as keelboat control lines.

Built with a lightweight composite cheek, rope friendly Ultra-Strap and Dynamic bearings

Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.

Ultra-Strap – Our patented Ultra-Strap is used in our 20, 30 & 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs. The Ultra-Strap was the first marine industry block designed to work specifically with a rope attachment.

Becket - The 40mm range features a large central hole, which is designed to be used as becket (tying off point).
