Schebler engineered stacks are designed and built to save you time and lower costs while bringing safety and satisfaction to your high-level projects. Our high-quality engineered stacks vent fumes at high elevations, away from other buildings and environments. Each is completely custom-designed to fit your needs and your existing chase, with a minimal existing lateral support structure. This single- and double-wall design increases the capabilities for exhausting high-temperature boiler exhaust gases.
