Description The Allen 20mm Forehead block is most commonly found on the foredeck of a Laser for the Cunningham and outhaul systems. It can also be used for other dinghy and windsurfing due to it being low friction and fast rolling. The A2020 is a 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. Articulating Fork Head – This block features a fork head with a threaded pin. The block can also articulate on the attachment fitting.
