When mounting the ashtray on the wall, pick a sturdy mounting point and place receptacle between 36”-42”above ground – and level. Once in place, remove ashtray pocket from receptacle and place back on wall to mark hole centers. Use appropriate concrete anchors; the size of the anchor will be slightly smaller than the holes. For wood use #10 x 1” wood screws. Make sure when installing, to re-install garbage can and check that it is level, once it is level, finish installing anchors and hang the receptacle back on the wall.
