## Questions & Answers

**Q: What is better? Porcelain or stainless steel?**
A: These steel ones are very good and solid. Had them for a few years now and they are still solid.

**Q: Will they fit Char Griller 5030?**
A: The shield is adjustable.  If the size of your old shields is within the range of this product then it should fit.

**Q: I have a char-broil model 463241113 4-burner.  i do not see the specific model here, but the dimensions seem to work.  do these work for my grill?**
A: Yes thay adjust to 21 inches long 
Thay work perfect on my grill. Its a good buy!!

**Q: Will this fit my Charbroil 2 burner grill ?  model 463621615**
A: I can't say if it will fit your charbroil, as I have a different brand.  The only thing I can say is measure your grill and check it against the 
measurements of the insert.  Check out the pictures on Amazon against what your insert looks like.  That is what I had to do.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked like a charm.
*by T***N on June 20, 2026*

I bought these Unicook replacement heat plates for my aging gas grill, and they worked perfectly. The adjustable range from 11.75" to 21" allowed me to slide them to the exact length of my original heat tents.The porcelain-coated steel feels much heavier and thicker (1.2mm) than other aftermarket brands I looked at, which gives me confidence they will last a long time. The included M5 stainless steel bolts and wing nuts made assembly straightforward and completely tool-free. Since installing them, the heat distribution across my grill grates has been more even, and I have noticed a major reduction in flare-ups. It is an excellent, cost-effective alternative to expensive OEM manufacturer parts

### ⭐⭐⭐⭐⭐ Great product!!!
*by W***H on August 22, 2026*

I was totally satisfied with this purchase. The instructions were user friendly and not being particularly handy, i was still able to complete installation of the product. Additionally, the price point for this item was appropriate. I would definitely recommend this item.

### ⭐⭐⭐⭐ Heavy-duty and versatile, but check your measurements first
*by L***S on May 2, 2026*

​I purchased this 5-pack of Unicook Adjustable Heat Plates to replace the rusted-out flame tamers on my gas grill. Overall, I’m impressed with the build quality and the flexibility they offer. ​ The Good: ​Heavy-Duty Material: The porcelain steel feels thick and durable. It’s a significant upgrade over the thin, flimsy shields that often come standard with mid-range grills. ​ Highly Adjustable: The ability to slide these from 11.75" all the way to 21" is the biggest selling point. It makes them compatible with a huge variety of brands and saves you the headache of hunting down brand-specific parts that might be discontinued. ​ Great Value: Getting a 5-pack at this price point is much more budget-friendly than buying individual OEM replacements. ​ Things to Watch Out For: ​Width is Fixed: While the length is adjustable, the 3.75" width is not. Make sure your grill's burner layout can accommodate this width without overlapping or leaving too much of the burner exposed. ​ Hardware Assembly: They come with M5 bolts and wing nuts. They are easy to install, but I’d recommend tightening them down well so the plates don't slide out of your desired length when you're cleaning the grill later. ​ Final Verdict: If you want to extend the life of an older grill without spending a fortune on original parts, these are an excellent choice. They distribute heat evenly and protect the burners well. Just double-check your width requirements before ordering!
