Why Use a Charcoal Firebox in a Kettle Grill
A charcoal firebox helps organize charcoal inside the grill, improving heat control and fuel efficiency. Benefits include:
- Longer burn time with fewer charcoal refills
- More stable cooking temperatures
Struggling with messy charcoal ashes? The removable ash basket makes cleanup fast and simple — no more wasted charcoal or dirty grills.
Designed to span the entire width of your Weber 22" kettle, this basket maximizes your grill's capacity. It holds a massive amount of charcoal and wood chunks, eliminating the need for messy mid-cook refueling. Whether you're hosting a 4-hour family BBQ or a 12-hour smoking marathon, this basket has the capacity to keep the fire going.

I love this. I stopped using this grill because of flare ups but with piece , I will still get the heat required but not worry about flame flare up and the ash will still go into the ash collector. I love it. It‘s easy to put together but I put the grill hooks on first and then the bowl, made it easier. Definitely worth the money. Well made and they packaged it very well. Enjoy

This is a good quality firebox, used it for the inside of a custom whiskey barrel smoker that I just built! I wish it came with the ash basket as well but it was okay to purchase that separate. I like the onlyfire brand for the price point, as it compares to name brand bbq gear.

Great upgrade for any 22" weber kettle

I‘m really impressed with this heat deflector and basket set. The pieces are sturdy, well made, and fit perfectly into my grill. The ceramic plates are smooth and solid, and the basket holds everything in place with no wobble. It already feels like it’s going to heat evenly and make low-and-slow cooks so much easier. I love it and can’t wait to smoke some meat.

Very simple to assemble. Turns your 22 inch Weber into an expensive kabado. For 135 bucks. It will be the best money you ever spent on your old Weber! Once that ceramic plates get hot, they stay hot for a long current time. Perfect for briskets and pork loins and anything you want to cook low and slow. But it's also capable of intense heat and I can attest to over 700° with my pizza cooker attachment.

I decided to go big or go home. As you will see in the pictures there was a lot of charcoal in that basket. The radiant heat from the stone below the great did an excellent job. Cooking through the chicken thighs to 195° internal temperature, in less than a half of an hourI think my next cook will be chicken wings dredged in flour. I’m curious to see if they will be like an air fryer cook. I will update.ImUpdate:11/12/2023 LOW AND SLOW TO HOT AND FASTI used the Weber baskets pulled together in the middle filled with a chimney of unlit charcoal. I spread chips over the unlit charcoal and poured a half chimney of lit coals over the pile of unlit chips and charcoal. I closed the bottom vent to a sliver open and left the top vent fully opened. The grill held a steady grate temp of 250-265°I smoked chicken thighs for one hour then opened the bottom vent. In ten minutes it was up to 400°+. The thighs finished with a flavorful crispy skin.

Quality seems great - although I was not able to try it out giving this is just an insert to the kettle that needs to be purchased first. I thought I had bought the whole thing - not just the inside containers beware of the actual contents of this ad

excellent addition. heat retention is great. fewer coals, longer burns.
the pizza stone is a nice addition, works well!

Fits perfect in Weber and easy to fit/install the pieces. The deflector worked perfectly for baking a pizza directly on a pizza stone on top of the grill. The deflector is heavy duty. We are able to cook Mongolian grill or Korean BBQ without destroying the aluminum drip plate they come with. I highly recommend to expand grilling possibilities.

Retains heat, reduced charcoal cost, keeps my Webber kettle in a very consistent and manageable temperature

Great

First low and slow cook with the insert and it turned out well. Even on a windy cool day (high 30s to mid 50's F) I had no trouble getting to temp and it holding rock solid for the whole cook.

This is perfect for those long smokes on the weber kettle. Held temps steady at 275 for over 8 hours on 1 basket of charcoal. The pizza stone on top is a great heat diverter preventing hot spots and flare ups. Ribs came out perfect, Next week is brisket.

Directs heat upward so that I can sear I my Weber just like a 600 dollar green egg

I used this set for the first time last Sunday, set up was easy and straight forward. I used it to make a rotisserie chicken that turned out great. The even heating it provides allowed me to cook the chicken in about one hour and fifteen minutes. It had a crisp skin and remained moist inside the chicken. The next use will be to do a slow cook of a pork shoulder. Cheers!

I actually loved this. It makes the temperature on my Weber grill very stable so once I set it I know it will maintain. Used it for smoking and grilling. Highly recommend it!

THIS IS AN AWESOME UPGRADE TO YOUR WEBER 22" KETTLE, FIT ,FUNCTIONALITY, EASE OF USE. WORKS AS ADVERTISED HELPED STABALIZE AND HOLD TEMPS WHERE I WANTED THEM TO BE ON THE 3 COOKS I HAVE USED IT ON SINCE THE WEEK OF THE 4TH OF JULY. WELL PACKAGED AND EASY TO INSTALL, TOOK ALL OF 5 MINUTES. WORTH EVERY PENNY. HIGHLY RECOMMEND.

Great economical way to upgrade your weber to be similar to a ceramic style grill. I made sure to season the ceramic parts with oil to help keep things from sticking. Very happy with the how it works. I did rivet the grill grate tabs to the grill because they did not want to stay in place, but that was a minor inconvenience.

This accessory is a must-have for low and slow kettle cooking. I am able to regularly get 12+ hour cooks at low temperatures with one chimney of charcoa. If I fill it up with charcoal, I can get 20+ hour cooks.This will save money in charcoal alone over time.

Got this approx 10 months ago. Worked great. Really made my Weber into a Big Green Egg for a fraction of the price. However, we dipped below zero (which rarely happens in Northwest Arkansas) and the diffuser split in half. Contacted customer service. No questions. No problem. A replacement was sent. So happy with the product and the outstanding customer service!

Used this heavily with my Weber kettle and it is absolutely game changing for smoking. Once dialed in, it keeps temps within 0-25F variations instead of 0-50f without.Keep in mind that it will reduce the charcoal space within the kettle, thus you are limited in certain attachments such as SnS baskets.I had used this heavily for one season. Unfortunately the main center stone had cracked after I had left the kettle vents open to burn/clean. Keep in mind that these ceramic plates will behave like a Kamado, and thus will need to require slower temperature variations (i.e. don’t dump a whole chimney full of lit charcoal into a vortex and place the center stone over it).I contacted OnlyFire CS and they graciously offered me a whole new kit free of charge (not just the center stone, but a whole new insert).10/10 must have for any Weber kettle.

I did my snake cook with the Onlyfire, and it was great. I used the conical charcoal holder to help keep the snake burning. Cooked a Pork Shoulder.Keeping the temperature steady was a learning experience.Lesson #1: Make sure your snake is even without bunches of coals; this can really drive the temperature up. Lesson #2: Keep the bottom vent; use the top to control heat.Lesson #3: Calibrate the thermometer on the top of your Weber with a digital meat thermometer you trust. I have a 30-degree difference.This is a bit more work than a Traeger, but the outcome is worth it. The smoke flavour from Charcoal is milder and less pronounced than pellet smoke. This allows the taste of the meat to come through. I can't wait to taste a smoked Chicken.

I love how I can cook something low and slow with a ceramic insert that retains heat really well. I would buy this again if needed or as a gift for the grill enthusiasts I know. You need to know how to grill somewhat to get the maximum benefits.
