Buying Guide
What should you look for when buying grill burner covers?
- Length and width: Ensure the plate length matches your grill’s burner configuration and mounting slots. Two common lengths are 11.75″–21″ and a fixed 14.56″ in some models.
- Material: Porcelain-coated steel offers durability and heat resistance, while 18-gauge thickness typically lasts longer than thinner options.
- Compatibility: Check model numbers and slot dimensions for Nexgrill, Char-Broil, Grill Master, Kenmore, and similar brands. Flexible designs help, but verify before ordering.
- Number of packs: Choose a pack size that matches the number of burners on your grill to simplify replacement and avoid extra parts.
- Installation: Look for parts with included hardware (bolts and wing nuts) and straightforward install instructions to minimize downtime.
- Heat management: Replacement heat tents and shields protect burners from grease and flare-ups and promote even heat distribution.
