Oklagarden Reversible Cast-Iron Grill Grate for Dyna-Glo DGH474CRP/DGH450CRP 16.4" Heavy-Duty Heat-Retaining Sear Grate

These Oklagarden reversible cast-iron grates replace Dyna-Glo models (DGH474CRP, DGH450CRP, DGH483CRP, DGH485CRP) to restore even heating and crisp sear marks on your grill.

If your Dyna-Glo grill needs a durable cooking surface, these heavy-duty cast iron grates are made to match original fit and performance. Constructed from thick matte cast iron, the grates hold heat well for steady cooking, create restaurant-style sear marks, and can be seasoned to develop a naturally nonstick finish. The design is intended as a direct replacement for several Dyna-Glo part numbers, so you can swap them in and get back to grilling quickly.

Will these grates fit my Dyna-Glo model?

These grates are produced to fit multiple Dyna-Glo part numbers commonly used across several grill models. Confirm the exact grate dimensions and your grill's replacement part number before purchasing to ensure compatibility.

• Compatible with DGH474CRP, DGH450CRP, DGH483CRP, DGH485CRP and related models.
• Cross-references original Dyna-Glo part 70-01-911.
• Single piece measures approximately 16 4/9" length — check against your existing grate.

How do these cast-iron grates improve cooking?

Cast iron stores and spreads heat more evenly than many lighter materials, which helps maintain stable surface temperature when searing or grilling dense foods. The raised grid pattern produces visible sear lines and encourages caramelization without excessive flare-ups.

• Thick cast iron construction improves heat retention and steady cooking.
• Grid lines deliver classic sear marks for steaks, vegetables, and fish.
• Reversible design gives even wear and extends usable life.

What maintenance does a cast-iron grate require?

Cast iron does best with a simple routine: clean while warm, dry thoroughly, and re-season with a thin layer of oil to protect against rust and build a nonstick surface. Avoid soaking or using harsh detergents that strip seasoning; gentle washing and immediate drying are recommended.

• Wash with warm water and a soft sponge; avoid abrasive chemicals.
• Dry completely, then brush with vegetable oil and heat to set the seasoning.
• Store indoors or covered to prevent rust when not in use.

How do I install and check fitment quickly?

Installation is straightforward: remove the old grate, position the replacement into the same slots, and ensure it rests level and stable. If the grate does not sit flush or match slot spacing, double-check part numbers and measured dimensions before forcing it into place.

• Remove old grate and clean support rails before installing replacement.
• Place the new grate into existing slots; it should drop in without modification.
• Measure the supplied 16 4/9" length against your current grate if unsure.

Who is this for: Grillers who own Dyna-Glo units requiring a durable, heat-retaining cooking surface will benefit most from these Oklagarden cast-iron grates. They’re ideal for weekend barbecuers, serious sear-seekers, and anyone restoring or maintaining older Dyna-Glo grills who needs a near-original replacement that seasons into a dependable, long-lasting surface.
