Allen 30mm High Load Single Block Maffioli Control Lines Companions to our popular Harken30mm 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.

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