Hey there! I've been using a commercial bakers rack https://www.amgoodsupply.com/storage-shelving/bakery-racks/ for a while now, and it's been a game-changer in my bakery. One crucial factor to consider when purchasing is the spacing between the shelves. Make sure there's enough clearance to accommodate your tallest items comfortably. Additionally, think about the environment the rack will be in. If your bakery tends to get humid, you might want to look for a rack with rust-resistant coating to ensure longevity. As for where to buy, I've had good experiences with both online restaurant supply stores and local commercial kitchen equipment vendors. It's worth checking out both options to compare prices and find the best deal!
