RONSTAN Orbit ratchet block, 1 sheave with automatic and manual ratchet function.
The RONSTAN Orbit Blocks are particularly lightweight in relation to their workload. For fixation these blocks have rope loops of Dyneema ® SK75 – a lightweight and very flexible method to attach blocks. The loop is held by a clip on the block. Even when opened, it remains firmly connected to the block on one side. A unique asymmetric bearing system reduces the tread on the active area of the washer, thus reducing the friction to a minimum.
