Pulling rusty internals out of the firebox leaves a messy pile of flaky metal on the patio. We put together these replacement burner tubes and porcelain-enameled flavor bars to refresh the inside of your three burner cabinet grill in one go. Check your knobs first, as these drop into front-control models only.

Porcelain coated flavor bars

We press these heat plates from heavy steel and coat them in porcelain enamel. They catch grease drippings above the flames, spreading the heat evenly across the firebox while protecting the tubes below from sauce and salt.

Matched burner tube set

The burner tubes and crossover piece are formed from stainless steel with clean, spaced gas ports. They direct the flame smoothly along each channel, so the fire stays consistent from the front of the cookbox to the back.

Front control cabinet fit

This set is shaped specifically for three burner grills that carry their control knobs along the front face. If your grill mounts its control valves on the right side shelf instead, these tubes and bars will not seat correctly.

Checking the model list

Take a look at the data tag inside your grill cabinet before you start loosening old screws. Match your grill against the models we list beside this page to be sure the mounting tabs line up with your firebox.
