What type of support is necessary for nonmetallic auxiliary gutters at each end or joint?

For nonmetallic auxiliary gutters, secure mounting is essential at each end or joint to ensure proper stability and function. Nonmetallic materials can rely on secure mounting to maintain their position and prevent sagging or displacement over time. This method provides the necessary support to withstand environmental stressors and ensures that the gutter system operates effectively without leaks or failures.

Brackets, support straps, or other forms of hardware might be useful in certain scenarios but are not specifically stipulated as necessary for nonmetallic gutters. The design and characteristics of the nonmetallic gutters mean that they can often be mounted more simply without additional support brackets or straps, making secure mounting the key requirement in this case. Thus, focusing on securely mounting the gutters at their joints ensures they hold up effectively during use.
