Optimize corner cabinets with a lazy Susan set. Sturdy polymer plastic trays with robust rib construction make for a secure shelf. Telescoping pole locks in place at your desired height. Each shelf is independently rotating, and kidney hubs have a positive stop, so cutout stops at the door opening. Each unit is tested to exceed BHMA Class-1 specifications of 20 pounds per square foot for 75,000 cycles. Set includes shelves, pole, all mounting hardware, and installation instructions.
