High Load - XHL and XXL Blocks

The range of High Load Blocks from Allen is expanding with additions such as doubles, triples and Tii-On’s now available.

Allen High Load Blocks fit between the standard dynamic range and the XHL range. The blocks feature a stainless-steel sheave which runs on a double race of stainless-steel ball bearings.

By utilising a stainless-steel sheave with a slight V shape profile, the Allen High Load range offers the ability to be paired with both wire and Dyneema®. This design also reduces deformation of the sheave under high static loads. These combinations result in less friction, higher working loads, better performance and durability over the acetal sheave Dynamic Block range.
