Final answer:
The best practice for eaves trough hanger spacing is to follow the manufacturer's guidelines to ensure proper support and functionality of the eaves trough.
Step-by-step explanation:
When installing eaves troughs, the best practice for hanger spacing is to follow the manufacturer's guidelines. These guidelines are carefully designed to ensure that the eaves trough will be properly supported and will function as intended. Manufacturers typically recommend spacing hangers at specific intervals that could vary from one product to another, so it's important to consult the product documentation. As a general rule, though, hanger spacing might fall anywhere between every 1 foot to every 3 feet, depending on the design and expected load on the eaves trough. Choosing an option like 1/2 foot or 1 foot without reference to the manufacturer's guidelines could lead to improper installation and potential damage.
