A2028HL - 20mm block - Opposite flat - high load - MWL=300Kg
Back To Back High Load - 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 the 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. Our back to back blocks feature two sheaves, both with our patented dynamic bearing technology. The sheaves face opposite directions to allow two control lines to run at a maximum of 180 degrees to each other. Held together with a strong stainless steel side strap and nylon mouldings ensures the block will not separate even under two very high opposing loads. The strength of the design lends itself to be tied around the middle in the slight V shape, meaning it can be used in applications such as triangle backstay systems found on sport boats. One of the more popular applications is in a dual pole and spinnaker launcher system such as the system commonly found on a 49er.
