20mm Single high load block.
The Allen 20mm dynamic ball bearing block is simply the best designed and engineered micro block on the market.
Featuring Allen's high load stainless steel sheave & dynamic bearing system to withstand extreme loads.
Allen High Load Blocks fit between the standard dynamic range and the XHL range featuring 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 in comparison with acetal sheave versions.
