Lodge 20 x 10.44 Inch Pro-Grid Reversible Cast Iron Grill/Griddle
This Lodge pro-grid reversible surface is a versatile cast iron product that combines a ribbed grill on one side with a flat griddle on the other.

The product emphasizes its PFAS-free and non-toxic construction, aligning with Lodge’s long-standing emphasis on safe, seasoned cast iron. The dual-sided configuration—grill on one side and flat griddle on the other—offers flexibility for searing a steak and then finishing with eggs or pancakes without switching cookware. This model illustrates how cast iron pieces can adapt to multi-burner layouts and variable cooking tasks on a single grill platform.

The extensive compatibility list demonstrates the broader applicability of cast iron burner replacements in multi-brand grills. When choosing, verify model numbers and burner dimensions to ensure a proper fit, particularly when working with turbo or high-output grill configurations that benefit from robust heat distribution.
Direct Store DB101 Four-Pack Cast Iron Burners
This four-pack from Direct Store features 15 13/16-inch long burners with a 2 3/16-inch width. They are marketed as replacements for JennAir and Nexgrill models among others, with reference to several specific part numbers. The kit’s emphasis on measurement and fit helps buyers avoid mismatches while offering multiple burners per grill to match long-term replacement cycles for high-use grills. Cast iron’s heat retention characteristics remain a central advantage for even cooking on larger grill units.
Buying Guide
- Size compatibility: Measure burner length, width, and mounting points before purchasing. Even small variances can affect fit and gas flow.
- Brand and model matching: Check your grill’s model numbers and the listed compatible part numbers. When in doubt, contact the seller for confirmation.
- Material and durability: Cast iron provides excellent heat retention and even distribution but requires proper seasoning and maintenance to prevent rust and sticking.
- Heat output and durability: Replacement burners should withstand outdoor conditions, resist warping, and maintain steady flame over time for consistent cooking results.
- Maintenance considerations: Look for burn-in notes, cleaning recommendations, and whether the burner comes with a warranty or customer support options.
- Installation complexity: Some burners use simple bolt-in replacements, while others may require disassembly or additional components such as burner tubes or grates for full compatibility.
- Multi-pack value: If you own multiple grills or a high-use grill, bundles (like 3-pack or 4-pack sets) can offer cost savings and easier replenishment over time.
- Safety and compliance: Ensure any replacement parts meet your grill’s safety standards and that you follow manufacturer guidelines during installation and testing.
- Temperature consistency: Cast iron can improve heat distribution, but ensure the replacement does not restrict gas flow or alter venting characteristics of the grill.
Overall, selecting cast iron burners hinges on precise sizing, verified compatibility with your grill model, and proper maintenance to preserve heat performance. The options reviewed here illustrate a spectrum from multi-brand compatibility to high-precision, brand-specific replacements, all aimed at restoring or improving grill performance with durable, long-lasting cast iron components.
