Trapeze hangers are used for hanging larger duct.

• A. True
• B. False
• C. Not used for duct
• D. Only for piping

Answer: (A)

When supporting large ductwork, you need a system that distributes the weight and keeps the duct aligned. Trapeze hangers achieve this by using two parallel members (like straps or channels) connected by a crossbar and hanging from threaded rods or similar supports. That creates a trapezoid shape that cradles the duct and suspends it from above. Because the load is spread across the two hangers and along the crossbar, the duct stays level, reduces stress concentrations on any single point, and can be adjusted easily for proper alignment. This makes trapeze hangers the go-to choice for large-diameter or heavy-gauge duct, where a single-point hanger would risk sagging or misalignment.
