Jenn Air Grills

Costco Jenn-Air Nexgrill Heat Plate. 17 3/4″ x 6 15/16″. The front to back dimension (depth) is critical to rock grate fit. As a general rule, a replacement grate (angle or heat plate) must be within three sixteenths of an inch () of the original part in this dimension to fit. You should measure your grill to make sure the replacement grate will fit before buying a part with a front-to-back dimension different from the original part. The width of a grate is much less critical. A replacement can be a few inches narrower than the original and still be useful.
