The most useful way to check whether this thermometer fits your grill is to compare it with your original one, especially the Tab on the back of the head.

Please note this 67088 / 67731 thermometer is totally different from the #60393 thermometer, which looks really similar to each other.
The former has a tab on the back of the head, but the latter one does not!
The mounting tab is used to fits into slot in the bezel to secure the position of the gauge.
