What is the largest pipe size that can be hung from a toggle hanger?

The correct answer is 1½ inches because toggle hangers are specifically designed to support lighter loads and smaller pipe sizes. When installed properly, toggle hangers provide adequate support for pipes that are up to 1½ inches in diameter. This sizing is crucial as it ensures that the hanger functions effectively within its designed capacity, preventing strain that could lead to failure or damage.

Larger pipe sizes, such as 2 inches or 2½ inches, exceed the typical load capacity of toggle hangers and may require different types of hangers or supports that are better suited for heavier or larger pipes. For pipes that are 1 inch or smaller, other more appropriate types of support may be used, but toggle hangers are particularly optimal for the 1½ inch size to maintain system integrity and stability.
