This instructional video demonstrates the proper method for fabricating a three piece 90° elbow using QuietR® duct board. The video begins by identifying the required tools and personal protective equipment, including safety glasses, a tape measure, and a duct board knife.
Using a standard 4 foot straight duct board module, the video walks through each step of the fabrication process, which can be easily completed at the job site. Viewers are shown how to locate and mark the center point of the duct board module, then measure and mark 2 inches on either side of center to create a 4 inch elbow throat. The video continues with step by step guidance on aligning the template, marking cut lines, and completing the required cuts. Additional steps include folding, assembly, and proper taping techniques to ensure a secure and finished elbow.
The process concludes with a completed 90 degree duct board elbow, highlighting an efficient, accurate, and repeatable fabrication method for HVAC applications.
