A2021F - Single With Articulating Fork Head
20mm Single Dynamic Block With Articulating Fork Head.The A2020 is our go-to low friction, fast rolling, small pulley. It's lightweight and strong, making it ideal for dinghies, windsurfing, kitesurfing and anything else that runs smaller diameter lines. Our Dynamic range is generally the best choice for applications that require constant sheave movement.Articulating Fork Head - This block features a fork head with a threaded pin. The block can also articulate on the attachment fitting.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.
