The Certainty of High-Performance Prefabricated Products

Our factory-built grease ducts are built for the ultimate in reliability, delivering maximum safety and performance.

Designed to meet the most stringent design criteria, our UL 1978 listed products comply to all code and fire safety requirements, including NFPA and IMC or UMC codes. As a result, commercial kitchens are safer, and exhaust systems work better.

Unlike traditional field-fabricated systems, our made-in-the-USA prefabricated systems have unmatched quality control and provide many advantages in installation and reliability, with no on-site welding or secondary installation needed. No fire-rated shaft is required for products that are UL 2221 classified, saving you time and expense, as well as space.

An Exclusive Gasket Connection

Our first-of-its-kind gasket connection gives our grease ducts the certainty of safety and reliability. Our unique flange-to-flange, factory-applied design meets UL 1978 listing requirements while lowering costs and allowing for faster installation.
