Fire Sprinkler Trapeze Modulus Calculator Icon

Trapeze Sizing Calculation App

Summary: This program calculates the minimum required trapeze modulus required based on NFPA 13 requirements and the correct application of the data obtained from the use of this program is the responsibility of the user. This software is not a substitute for technical knowledge of structural analysis or NFPA 13 requirements.
