    General Information

    • Model Number G438-0100-W1B
    Firebox Grill Bottom is rated 3.7 out of 5 by 6.
    Rated 5 out of 5 by from Easy assembly My grill is 6 years old and fire box rusted out. So we figured just get a new box because the rest of the grill is still in good shape. No sense to buy a new grill. Installed easily everything is just bolted together. Gave other parts a touch up with black enamel paint and whole thing looks new again.

    Rated 5 out of 5 by from Simple This was a great fix for my grill. I have had this grill for almost 8 years and I needed to replace the firebox. It was a fairly simple job, took me maybe an hour or two.

    Rated 1 out of 5 by from Not impressed Would not purchase char broil again. Product is cheap, it all rusts and deteriorates even with cover when not in use. Firebox was not fun to replace

    Rated 2 out of 5 by from Difficult to replace This part is very difficult to replace. It would be much easier to replace just the bottom plate if it was available as a separate part.
