Allen 30mm Single High Load Dynamic Block With Fork Head.

High load blocks feature a stainless-steel sheave. This upgrade offers even faster rolling speeds, higher working loads and lower friction when compared to the standard acetal sheave.

The stainless-steel sheave allows the block to be paired with both rope and wire.

Ideal for use in higher loaded applications in dinghies, windsurfing, kitesurfing and anything else that runs smaller diameter lines.

Fork Head‚ This block features a removable clevis pin to make the attachment of this 30mm dynamic single block super easy.

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.

Becket‚ Our 20 & 30mm blocks offer a large central rivet which not only reduces the overall weight but also offers a rope friendly attachment, perfect as a tie-off point when being used in a cascade system.
