Key specs explained
Material: Cast iron
Cast iron retains heat well and distributes it evenly across the cooking surface. This helps you get consistent sear marks on steaks and vegetables without hot spots. The material is heavy and durable, meaning it lasts longer than thin steel grates. You will need to season these grates regularly to maintain their non-stick surface and prevent rust. This is a standard choice for outdoor grilling when you want that classic charred flavor.
Dimensions: 17" x 7", 17" x 10 1/2"
The kit includes two narrow grates and one larger grate to fit the specific layout of your grill. This configuration allows you to cook different amounts of food on separate zones. You can place smaller items like burgers on the narrow sections and larger cuts on the wide one. These exact measurements ensure a proper fit without needing any modifications. Check your grill’s interior space to confirm these dimensions match your current setup.
Compatible Grill: Charbroil Performance 4 burner
These grates are engineered specifically for Char-Broil Performance four-burner models. They are designed to replace original part numbers like G426-0005-W1. This direct compatibility means you do not need to adjust the grill structure. It also fits various other Char-Broil series and some Kenmore or Broil King models listed in the data. Verify your grill’s model number before purchasing to ensure a secure and safe fit.
Grate Type: Cooking grate
This is a primary cooking surface designed to hold food directly over the heat source. The solid rods provide sturdy support for heavy meats and vegetables. Unlike warming racks, these grates are built for active cooking and searing. The cast iron construction helps release the original taste of food while providing a non-stick finish over time. You will use these daily for grilling, so their durability and heat retention are key factors.
Design and build quality
The listing states these grates are made from thick cast iron. This material choice means the grates retain heat effectively and distribute it evenly. You get consistent cooking results without cold spots. The finish is black, which is typical for seasoned cast iron. According to the listing, this solid construction prevents coating peeling and supports longevity. You do not need to modify the grates for a proper fit. The design prioritizes durability over lightweight handling. Cast iron is heavy, so you should be prepared to handle the weight carefully when cleaning or replacing parts. This build style suits users who want traditional searing capabilities rather than quick heat-up times.
The kit layout includes two narrow grates measuring 17 by 7 inches and one larger grate at 17 by 10.5 inches. This configuration covers the full cooking surface of compatible 4-burner models. The rod design is solid, which helps maintain structural integrity under high heat. The dimensions are fixed, so you must ensure your grill model matches the specified Char-Broil part numbers. The design does not include adjustable components or complex controls. It is a straightforward replacement part. You install it directly into your existing grill frame. The size and shape are engineered to match the original equipment manufacturer specifications. This ensures stable placement during cooking. The build focuses on function and compatibility rather than aesthetic features.
Setup and everyday use
Installation involves placing the grates directly into your grill. The listing confirms no modification is needed for a proper fit on compatible Charbroil Performance 4-burner models. You simply swap the old parts for these replacements. The kit includes two narrow grates measuring 17 by 7 inches and one larger grate at 17 by 10.5 inches. This configuration matches the specific layout of the target grill, ensuring the rods align correctly with the burner tubes below. For daily use, the thick cast iron construction requires you to season the surface before first cooking. This process creates a natural non-stick layer that protects the metal and helps release food easily. The solid rods provide even heating, which supports consistent searing for steaks and vegetables. Because cast iron retains heat well, you can maintain steady temperatures for longer cooking sessions. The material is durable and resistant to peeling, meaning the finish stays intact through regular cleaning. You should avoid using abrasive tools that might scratch the seasoned surface. The black finish is standard for this type of cookware and helps hide minor wear over time. These grates are designed to work with gas grills, as indicated by the compatibility with Charbroil Performance and Advantage models. They are not intended for charcoal or ceramic setups. Regular maintenance involves brushing off debris after cooking and applying a thin layer of oil to prevent rust. The sturdy build suggests these grates can handle heavy loads without bending. You benefit from the original taste release mentioned in the features, as the cast iron does not impart artificial flavors. This setup is straightforward for anyone replacing worn parts on a compatible grill.
Before you buy these grates
You should verify your grill model number before ordering. This set fits specific Charbroil Performance 4-burner units, including part numbers like 463365021 and 463350521. It also works with certain Kenmore and Broil King models. Check your owner’s manual or the old grate for the exact code. The kit includes two narrow 17 by 7 inch grates and one larger 17 by 10.5 inch grate. You must handle cast iron with care. Season the grates before first use to build a natural non-stick surface. Clean them gently after cooking to prevent rust. Do not use abrasive cleaners or dishwashers. Store them in a dry place. This product belongs to the outdoor cooking category alongside pizza ovens and griddles. If you own a Charbroil grill, these grates are a direct replacement. If you use a different brand, look for compatible options. Proper maintenance ensures the cast iron lasts for many seasons. Always double-check the fit to avoid installation issues.
