This basket is made of durable aluminized steel and will fit all Weber 22 inch kettle grills but also many other grills.
I will help you keep your charcoal briquettes on one side and help you to use indirect grilling.
I am using these myself on my smoker, in combination with the vents on there, to add just enough charcoal to keep my temperature low enough for cooking some great food.
They are very sturdy and will last you a long time.
I like the fact that all the slotted openings will give the air enough room to flow through the charcoal and this makes it easy to control the temperature.
It will hold a full load of charcoal that you started with your chimney starter or less if you do not need so much.
