Masterbuilt GS40 Gas Smoker

Masterbuilt’s 40″ Vertical Gas Smoker has large capacity with four chrome plated cooking racks that are approximately 22″ x 15″. Powered by a 15,400 BTU stainless steel burner, it features a porcelain coated wood chip tray and drip pan. The GS40 has two doors to facilitate replenishment of water and wood without opening the smoke box.

Many owners love these inexpensive BBQ smokers. Our posted MSRP from Masterbuilt is waaaay higher than the typical selling price. Check our Where To Buy section below to find this cooker for about half price.
