The Bar Mount System is used to attach the Elevated Pet Bowl to bars of a gate, crate or fence. It’s best to attach it to two bars for better stability. The bars can be no more than 2 3/4″ in length. The overall length of the mount is 3″. It includes a surface mount with a standard lever, a back plate and two (2) 3/4″ thumbscrews. The clip with this system is 3/4″ thick instead of the standard 1/2″ clip. A thicker clip is used if you want to hang a bowl under an overhang such as a shingle or siding.
