We are afraid that different manufacturers of different grills all take different dimensions and different customers take measurements in different ways.  So it is impossible to for us to guarantee fitment of accessories to any specific grill except TOPQ/YNNI units. We may be able to provide previous customer feed back if you supply us with manufacturer and model details of your grill. We do offer a return/ replacement service should items be unsuitable for your needs. Please note that return carriage is at the customers responsibility and cost. Alot of our Accessories have detailed measurements in the pictures and listings. if you require further measurements please let us know.
