Item #4154:The Pro Smoker is designed for those who make beekeeping more than a hobby. The stainless steel chamber is 4" in diameter and the full length with dome top is 11". It is all heavy duty high quality stainless steel. With reasonable care the chamber should last a lifetime, but with extended use the bellows may need to be replaced. A wire guard prevents direct contact with the hot chamber, and the hook provides a means to hang smoker for storing. A grate provides proper air circulation and is removable for easy cleaning.
