Unicook Adjustable Gas Grill Heat Plates 3-Pack — 11.75–21 in Length, Porcelain-Coated Steel, Stainless Fasteners

Unicook 3-pack adjustable gas grill heat plates are porcelain-coated steel burner shields that slide from 11.75" to 21" long and protect burners while improving heat distribution.

These replacement heat plates are made for a range of outdoor gas grills and are built to cut flare-ups, shield burners from grease and direct flame, and spread heat more evenly under cooking grates. Each plate measures 3.75" wide and features a heavy 1.2mm porcelain-coated steel construction; the set includes upgraded stainless M5 bolts and wing nuts for straightforward installation. Before ordering, check your grill's mounting slot width to make sure these plates will fit—if fitted in reverse they extend to about 18.37" instead of the full 21" length.

How do these heat plates change cooking performance?

They act as a physical barrier between flames and drips, reducing sudden flare-ups and helping heat move across the grill surface more uniformly. That makes searing and indirect cooking easier to manage and reduces hot spots beneath the grate.

• Porcelain-coated steel spreads heat for steadier temperatures.
• Barrier design prevents grease directly hitting burners and flames.
• Adjustable length lets you cover more burner area for consistent cooking.

Will these plates fit my gas grill and how do I measure?

Measure the width of the mounting slots or the distance between bracket supports where your current heat tents sit. The plate width is 3.75"; extended length ranges from 11.75" up to 21" depending on configuration, and a reversible installation yields an 18.37" option.

• Check mounting slot width to confirm compatibility.
• Standard 3.75" width fits many charbroil, Nexgrill and similar grills.
• Reversible installation provides a shorter extension if needed.

What materials and hardware come with the Unicook plates?

The plates are constructed from 1.2mm-thick steel finished with porcelain coating for corrosion resistance and easier cleaning. The package includes stainless steel M5 bolts and wing nuts to secure the plates without special tools.

• 1.2mm heavy-gauge porcelain-coated steel for durability.
• Stainless M5 bolts and wing nuts included for tool-free mounting.
• Porcelain finish wipes clean and withstands high grill temperatures.

How do I install and maintain these heat shields?

Installation replaces old heat tents or uneven burner covers—slide the plate into the mounting slots and fasten with the supplied wing nuts and bolts. For maintenance, scrape away large deposits, then wipe with a damp cloth; avoid harsh abrasives that could damage the porcelain finish.

• Slide into mounting slots and tighten wing nuts to secure.
• Scrape off heavy carbon build-up, then wipe clean.
• Inspect regularly for excessive corrosion or warping and replace as needed.

Who is this for: Home grillers who need durable replacement burner shields that fit multiple gas grill makes and want better heat control with less flare-up risk. This 3-pack suits people refreshing several burners at once, owners of medium-to-large grills who value adjustable coverage, and those who prefer included stainless hardware for easier installation.
