The Primo Extension Rack for the Oval X-Large puts a second tier of cooking space above the main grate. The grill stays the same size on your patio and gains a whole additional level of food.
The X-Large already has the cooking bed most people are buying Primo for, so the reason to add a tier here is rarely desperation and usually organisation. Slower items go up, the fast searing work stays down, and a cook that would have run in two shifts runs in one. On a long smoke it is simply more output for the same charcoal, the same vents and the same hours of attention.
Fits the Primo Oval X-Large ceramic charcoal grill and the Oval X-Large All-In-One package. It works well with the Primo 9-slot rib rack for the Oval X-Large when ribs are the whole point of the day, and with the Primo X-Large Griddle, which occupies the main level on its own. The wider range sits in Primo grill accessories.
