Like they say, designed for hauling systems where it's important to have symmetry - ie; for fixed sided pulleys.
Also, essential for creating a non-return pulley system with the Petzl Fixe pulley. Keeps the Basic ascender in correct alignment and doesn't make the pulley want to offset itself from vertical.
