Allen 20mm Single High Load Multi Function Block

The multifunction block has a slightly different strap compared to the A2020.

The multifunction head is designed to attach our swivel, fork and cheek adaptors too. It is also used for riveting to the double and triple ultra-straps.

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 application on dinghies, windsurfing, kitesurfing and anything else that runs smaller diameter lines.

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.
