Riveted racks are recommended for maximum weight loads of 200 lbs. They are easy to assemble and are shipped “knock down” for freight efficiency. All riveted racks are built to the standard 26” depth with the octagon nexus bars modified to accommodate the pan or tray width only. This is the most popular and economical way for you to purchase these racks. This also gives you the future option to change the bars to accommodate an 18” X 26” tray. If you wish to have the rack depth modified as well then we will gladly supply a custom quote to you.
