Unicook Adjustable Grill Heat Plate – Extendable from 11.75 in to 21 in | Porcelain Steel Heat Shield, 5 Pack

Upgrade your grill with an adaptable heat plate

The Unicook Adjustable Grill Heat Plate combines flexibility with durable construction to help you manage heat more effectively on gas grills. Made from heavy-duty porcelain-coated steel, these shield plates are built to withstand outdoor cooking and frequent use, while offering a versatile fit for various grill layouts.

Designed to sit directly above the burner, the heat plates extend from 11.75 inches up to 21 inches in length (3.75 inches wide and 1 inch tall). When installed in reverse, you can achieve a shorter extension of 11.75 to 18.37 inches. This adjustable system helps you tailor coverage to your grill space, potentially reducing flare-ups and protecting burner components during long cooks.
