The Grill adapter attaches a Jeep to a Universal Baseplate which allows the Zacuto baseplate to have 19mm studio, 15mm studio rods (Arri) or 15mm lightweight rods off the front of the baseplate. The track built-in to the Grill adapter allows you to adjust all rods to whatever lens height you need, like a built-in Z-riser. Left to right movement is achieved with the Zacuto baseplate.
