Reverse operation
If the running direction on your machine changes, we recommend using the appropriate Spann-Box® size with a long housing. We deliver this variant with heavy tensioning force.
Like Spann-Box® size 1, Spann-Box® size 2 is available in different variants. The steel housing guarantees durability and reliability. We offer four different designs in this size to meet your varied requirements.
