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.

Also available the High Load Blocks by Antal, these small and light blocks are the best solution for very high loads when sliding is not important. The very small sheave is fitted with a Composite Fibre bushing. The one piece frame is made for line connection.

Plus the XXL by Antal - The whole “composite fibre” range uses sheaves on composite fibre bearings and double self-captive Delrin ball thrust bearings.
