Allen Three 30mm Single Dynamic Blocks On Stainless Steel Ring.
The A2030R3 has been designed to be used as a backstay block on sports boats. It can also be used in a variety of other applications.
Bearings – Dynamic Blocks feature 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 – 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.
