Dang, I just gave mine to the goodwill thrift store with a box of junk.
Because they are junk. They barely hold anything.
Take an 18.5 in or smaller rack like one from a smokey Joe and some carriage bolts from Home Depot for the legs and you will have yourself a way more functional rack. Ive added a center rack and also made one of these for kettle my wsm 18 and my wsm 22. I get four racks in each wsm for big party's
see this one.
