This part was designed to allow a through-desk monitor mount to be mounted to an Ikea desk. With the mounts factory parts, the Ikea desk was unable to support a dual monitor stand with a 27" and 24" monitor combo. The top and bottom plates disperse the load enough so I no longer hear tearing sounds every time the table slightly moves :). Hope it helps!
