The innovative SPEED climbing protection runner is the world's only runner with two redundant catch systems and speed-dependent catch function. The catching bar is hidden in the housing and is protected there against unintentional intervention. Through an additional lever, the SPEED works like a back pull runner when climbing. The runner remains short and thus also the catch path. This provides climbing comfort and reduces fall-related injuries. In the event of a back pull failure, the runner can only reach a fixed preset maximum speed. If he exceeds this, the independently acting second safety device engages: a centrifugal brake swings out the catch bar and the runner blocks. The follower safety gear is compatible with C-profile rails of the SKYTAC rail from SKYLOTEC or the SOLL GlideLoc rail, which allows a variety of uses. Solid aluminum housing, stainless steel axles and metal guide rollers ensure low wear and tear.
