Catamaran / A-Class / Blocks / 20mm dynamic blocks
Our go-to low friction, fast rolling, small pulley. It’s lightweight and strong, making it ideal for dinghies, windsurfing, kitesurfing, paragliding and anything else that runs smaller diameter lines.
Available with a wide range of accessories and features to suit most control line applications.
Dynamic Bearings - Twin rows of stainless steel ball bearings running on a stainless steel axle provide superior rolling speeds and durability when compared to plastic alternatives.
Ultra-Strap – A stainless steel strap which holds the block together and provides a strong, reliable and rope friendly attachment point.
Becket – The hole through the middle of the block can be used as a tying off point (becket).
Maximum Working Load – If exceeded the block may not perform as designed.
Breaking Load – The load at which a major block failure is likely to occur.
