Unicook 6-Pack Adjustable Grill Heat Plates, 11.75–21 in

Unicook adjustable grill heat plates are replacement burner covers sold as a six-pack, with a listed extension range suited to grills whose heat shields need replacing. The adjustable fit is useful, but compatibility depends on both the original plate dimensions and the grill’s mounting slot.

At a glance

Adjustable heat shields are described as extending from 11.75 to 21 inches, or to 18.37 inches when installed in reverse.
The listing says the covers shield burners from grease drips and help spread heat toward the grill grate.
Upgraded stainless steel M5 bolts and wing nuts are claimed to be included for installation.
