Allen 20mm Dynamic Block with Swivel

The A2020 20mm Dynamic Block with Swivel Fork Head is the go-to choice for dinghies, windsurfing, kitesurfing, and any other activities that require smaller diameter lines due to its low friction, fast rolling design. As part of our Dynamic range, it features a swiveling fork head with a threaded pin and bearings that utilize our patented twin ball bearing system on a stainless steel rail for superior load-carrying ability and longevity. Additionally, its 20 and 30mm versions have a large central rivet for reduced weight and a rope-friendly attachment point in cascade systems.
