The Primo Extension Rack for the Oval Large gives the grill a second working level above the main grate. One fire, two tiers of food, and no change to the grill itself.

The case for it is strongest on a long cook. When ribs, pork or chicken are going to sit for hours, doubling the levels doubles what that fire is producing for the same charcoal and the same attention. It is also what saves a cookout when the main grate is occupied by something that covers it completely, since the upper tier stays free. Sitting higher above the coals, that upper level is the gentler of the two on a direct fire, which suits food that is finishing or being held rather than searing.

It is cut for the Primo Oval Large ceramic charcoal grill and no other size. Useful alongside the Primo Large Griddle or the cast iron searing grate for the Oval Large, both of which claim the main level, and with the Primo 5-slot rib rack when the cook is ribs. Further options are listed under Primo grill accessories.
