20mm Single High Load Dynamic 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.
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.
