I believe this is a universal heat shield. As long as the original heat shield wasn't longer than 21", this should fit.
when i bought mine, they were two in a pack.
Don’t waste your money on this thin piece of junk. I am sure it will burn through in 6 months or less .
Even when it's fully retracted?
It should fit. The width of your stock part is 3.8125", and the tent width is 3.75". The length can be adjusted to fit.
I can't find the "M" model at their site, but the key is the width of the included tamers. If they are close to 3.75" wide, then this part should fit.

Hello Wolf68, Robert from Nexgrill here. We would need to have your model number to verify, as long as the original flame tamers are between 11.4 - 18.5 in, they should fit. If you have additional question, please contact me directly at Roberto_Ulloa@grillservices.com. Happy Grilling!!!-Nexgrill
