Compatibility, Size and Fit
Use is limited to textile rope with a diameter no greater than 13 mm. Check the exact rope and the requirements of the complete system before selecting this pulley. The attachment point accepts up to three carabiners simultaneously, a configuration described for redundant safety systems; that detail alone does not establish suitability for a particular system.
Before You Decide
Confirm the rope type and diameter, and check that the planned setup stays within the stated 10 m/s maximum traverse speed. Follow the product instructions for setup and use.
