Thanks for contacting Tundra Restaurant Supply. The measurements between the legs on the Turbo Air TSW-2424E table are 15in X 15 /2in. A 20in pan would have roughly 2 1/2in overhang on each side. A TSW-2436E (product 95307) would fit your needs. Please see link below and contact our sales team if you have any other questions. Thanks.
