Go to appliance junk or used parts place .Find fridge with movable glass shelves,and check that shelf brackets are higher on back side where it attaches to fridge.When you set this unit on a level table top it will be lower in front and higher by an inch or so in back which gives the tilt to the glass sheif.I used a cheap adustable desk lamp that I articulated so as light shined under shelf from back.The glass on my shelf is marked tempered so you won't have large shards in case of breakage.Also get a smooth glass ,some are a litte rippled
