Our 6″ ball bungees are made with high quality long lasting heavy duty bungee cord. We only use HIGH GRADE RUBBER BUNGEES not discount store or most found on bidding web sites They are used to quickly and conveniently attach tarp to the frame. They are made to stay on the tarp (attached through the grommets) The concept is simple, the ball rests against the grommet on the tarp, and a loop wraps around the pipe of your frame or fence fabric of your kennel and loops over the ball. The elastic nature of ball bungees keeps the tarp taut securely in place. Useful to have in the gadget bag or around the home. Ball bungees can secure your umbrella to your light stand,  act as an improvised light stand, attach shopping items to your bike.  Great for securing hoses ,cables , pipes, lumber to your vechicle  or around your home  like a very strong band A 1001 uses!
