Uniflasy Cast Iron Cooking Grates for Dyna Glo DGF493BNP DGF493PNP – Two-Piece Matte Cast Iron, Heavy-Duty Heat Retention

These Uniflasy cast iron cooking grates replace the factory grates on compatible Dyna Glo and Kenmore 4-burner grills, restoring even heat and classic sear marks.

Made from matte cast iron and sized to match several Dyna Glo, Kenmore, Backyard and Uniflame models, these two-piece grates give you the heavy-duty cooking surface of OEM parts at a budget-friendly price. Each half measures 16 4/9 x 9 1/4" (total cooking area when combined is 16 4/9 x 27 3/4"), so confirm your original grate dimensions and grill model before ordering. The grates are designed for direct replacement of models such as DGF493BNP, DGF493PNP and other listed part numbers.

Will these grates fit my Dyna Glo DGF493BNP or similar model?

Yes — these grates are manufactured to match the footprint and mounting points of the DGF493BNP and several related Dyna Glo models. They also list cross-compatible Kenmore and Backyard model numbers, making them a practical swap for many 4-burner grills.

• Compatible with DGF493BNP, DGF493PNP and related Dyna Glo part numbers.
• Cross-referenced to Kenmore and Backyard replacement model numbers for broader fitment.
• Measure each original grate: half is 16 4/9 x 9 1/4" to confirm fit before purchase.

How does cast iron change cooking performance?

Cast iron holds and distributes heat more steadily than many stamped-steel grates, producing consistent searing, clearer grill marks, and steady cooking temperatures. The heavier metal is slower to heat but maintains temperature under food, which helps with even browning and improved crust formation on meats and vegetables.

• Improved heat retention for even searing and consistent results.
• Produces distinctive, darker grill marks for visual and flavor benefits.
• Thicker profile reduces hot-spot variance across the cooking surface.

What maintenance keeps these grates rust-free and long-lasting?

Cast iron requires basic seasonal care: clean off debris after each cook, re-season with a light coat of cooking oil, and avoid prolonged exposure to moisture. For storage, coat heavily with oil and keep the grates in a dry, covered space or wrapped to prevent condensation and rust formation.

• Scrape and brush grates after every use to remove food residue.
• Apply a thin layer of cooking oil when cool to maintain the seasoned surface.
• Leave grill dampers slightly open and cover the grill to reduce condensation.
• For long-term storage, heavily oil and wrap the grates in plastic inside a covered grill.

Are these OEM parts or aftermarket replacements — and what materials are used?

These Uniflasy grates are aftermarket replacements engineered to match the form and function of OEM components. They are cast from matte cast iron to reproduce the heat performance and durability of original cast grates while offering a cost-effective alternative.

• Aftermarket replacement manufactured to match OEM dimensions and mounting points.
• Matte cast iron construction for robust heat retention and longevity.
• Sold as a two-piece set to cover the full cooking area when combined.

Who is this for? These Uniflasy cast iron cooking grates suit grill owners who need a direct-fit replacement for specific Dyna Glo, Kenmore, Backyard, or Uniflame 4-burner models and who prefer the heat retention and searing advantages of cast iron. If you want a durable, budget-friendly alternative to OEM grates and are willing to perform simple seasoning and storage care, this set is a practical upgrade for backyard cooks who value consistent heat and classic grill marks.
