30mm Single High Load Fork Head Block With SA.873 Heavy Duty ILCA Vang Key.

This pulley comes with the SA.873 heavy-duty ILCA vang key. Specially designed to be used as the ILCA top Vang block.

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.

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.
