.This tarp hook screws on to the top of plastic bottles allowing you to use them to weigh down tarps. Use with tarpaulins by hooking the bottle top hook through an eyelet and use the filled bottle to weigh down your tarp to stop it blowing away in the wind. It's a clever solution that secures your tarp in situations where there may be no anchor point - a farmer covering hay bales in a field for instance. Fill the bottles with liquid, sand, gravel or anything else that fits. If your tarp or sheeting has no eyelets then combine Tarp Hook with a Hippo swivel Clip to secure and weigh down your tarps! Idea: Why not cut an opening in the side of a bottle to make a birdfeeder! Buy Online Now click here.
