When purchasing all my wall equipment I bought some sweet mats that hang up and have a no climbing picture on the underside when hung up to deter children from climbing when not in use. Unfortunately I thought the jugs and other holds I purchased sets of would accommodate and give a nice anchor point to hang the mats off of. Sadly they hardly worked, if a kid tugged hard enough the massive 4' x 6' would easily come down, not to mention it was a pain in the butt to get the cord to stay (kind of like bungee cord). With 4 of these installed I have 20 feet of mats comfortably hanging up with no worry at all of kids knocking them down (accidentally or intentionally). Also having these at the top makes for a perfect end to beginner routes as a final jug hold. So glad I stumbled on these, definitely better than trying to shop around and hope whatever jug I choose will be deep enough.
