Poulie Simple 30mm Dynamic.

Allen 30MM SINGLE WITH SWIVEL A2031SC

30mm Single Dynamic Block With Swivel Fork Head.

Swivel Fork Head – This block features a swivelling fork head with a threaded pin. The block can also articulate on the attachment fitting.

Bearings – Dynamic Blocks feature Allen 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 – Allen 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.
