If you use the Light Hanger for luminaries in a grow tent we recommend that you install the Light Hanger with the free end carabiner to the ceiling frame and the mechanism to the luminary as illustrated. This way, you will not put any stress on your tent frame when hoisting and it enables easier adjustment. For filters, we recommend that you attach the free end with the carabiner around the filter to avoid rotation of the filter when hoisting. Support the filter when hoisting it to avoid stress on your grow tent frame.Height Adjustment Adjust to the desired height by simply pulling the loose rope end. To release, hold the loose rope end and depress the lever recessed in the Light Hanger.
