Coulee Outdoors is a company driven to create sustainable, innovative products that connect people together while respecting and protecting the planet. Coulee Outdoor Firepits are constructed of durable, sustainable, top-quality materials making their pieces last for years! Coulee Outdoor Firepits are double wall constructed pulling air from the bottom and up through the vent holes that re-burn smoke as it rises to provide a more enjoyable, mesmerizing fire. The secondary vent holes aid in a secondary burn which allows the smoke to mix with the additional oxygen allowing significantly LESS SMOKE. This is what makes the experience around the campfire so enjoyable. 21" Burn Chamber (inside dimensions) Multi-Fuel: Firewood or Wood Pellets Adjustable Grill & Post Included
