The rope hanger is designed to hang various grow tent and ventilation equipment. You can easily push the carbineer hook to clip and secure your equipment. Then pull on the rope, which will automatically lock with the stainless steel ratchet mechanism. The rope is made of 1/8” braided polypropylene, and the hooks are constructed of zinc-plated steel. The internal gears inside the locking ratchet are all built with stainless steel parts for a long-lasting smooth operation.
