Description:

Upgrade your commercial kitchen exhaust system with this 18″ Double Wall Grease Duct Kit, engineered for reduced clearance to combustibles and rapid, weld‑free installation. The kit includes 10 feet of straight double‑wall duct plus dual 12″ transition connections, allowing seamless tie‑in to smaller hoods or fans while maintaining the safety of a fully insulated, code‑compliant system.

Built from high‑temperature, grease‑ and corrosion‑resistant steel, the double‑wall construction provides its own thermal barrier—eliminating the need for external wrap in most applications—while the no‑weld mechanical adapters cut labor time and keep downtime to a minimum.
