Unicook Adjustable Gas Grill Heat Plates 4-Pack, 11.75–21 in Length, Porcelain-Coated Steel for Even Heat & Flare-Up Reduction

Unicook's 4-pack adjustable gas grill heat plates are porcelain-coated steel shields that extend from 11.75" up to 21" to cover burners, reduce flare-ups, and even heat across most gas grills.

These replacement heat plates (sometimes called flame tamers or heat tents) are built to fit many popular outdoor gas grills including Char-Broil and Nexgrill models. Each plate is 3.75 inches wide with a 1.2 mm porcelain-coated steel body for improved durability and easier cleanup. The sliding length adjustment and included M5 stainless bolts and wing nuts make installation straightforward, and the design helps protect burners while distributing heat more evenly.

Will these heat plates fit my grill?

Measure the width of your grill's mounting slot before purchasing: the plate width is 3.75" and the minimum length is 11.75". When fully extended these plates reach up to 21"; reversed installation limits the extension to about 18.37".

• Plate width: 3.75 inches — check mounting slot width.
• Adjustable length: 11.75" up to 21" (reversed installs extend to 18.37").
• Compatible with many gas grills including Char-Broil, Nexgrill and similar models.
• Measure your existing heat tent or the burner-to-grate distance to confirm fit.

How do these plates improve grilling performance?

These heat plates act as shields between the burner and grill grates to prevent direct flame contact, reducing flare-ups and helping heat spread more uniformly across the cooking surface. The porcelain coating improves food release and simplifies cleaning while protecting the metal underneath.

• Minimizes flare-ups from drips, protecting food and reducing charring.
• Promotes consistent heat across the grill for more even cooking.
• Porcelain coating resists sticking and simplifies wipe-downs.
• Protects burners from grease and debris to extend burner life.

What materials and hardware are included, and are they durable?

Each plate is made from 1.2 mm porcelain-coated steel for a balance of strength and heat resistance. The pack includes upgraded M5 stainless bolts and wing nuts for a secure, tool-free installation. If parts are missing or you need help, Unicook’s customer support is available to assist.

• Construction: heavy-duty 1.2 mm porcelain-coated steel for durability.
• Hardware: M5 stainless bolts and wing nuts included for secure mounting.
• Optional stainless-steel version available from Unicook for extra corrosion resistance.
• Designed to replace heat tents for side-to-side and front-to-back burners.

How do I install and maintain these heat plates?

Installation is usually simple: slide the adjustable plate into the mounting slot, set the desired length, and fasten with the supplied wing nuts and bolts. For maintenance, let the grill cool, brush off residue, and wipe with a damp cloth; avoid harsh abrasives to preserve the porcelain finish.

• Installation: slide, extend, and tighten using included wing nuts and bolts.
• Cleaning: cool first, then brush off debris and wipe with a soft cloth.
• Longevity: avoid metal scouring pads that can damage the porcelain coating.
