Sizes: 3″, 4″, 5″, 6″ Rolled formed downspouts manufactured out of light gauge materials in 4 sizes, 10′ lengths. Custom sizing is not available. Commercial Gutter System Specifiers should consider using alternative downspout types if the downspout may be subjected to abuse or vandalism.

Commercial gutters tend be bigger and have a larger draining capacity than residential gutters, for good reason. Commercial facilities tend be larger than residential buildings, and there's often a much larger square footage of roof area to drain.

Distance from Structures: Downspout extensions should NOT be within six feet of a basement wall or two feet of a porch, crawl space, concrete slab or at-grade foundation. Additionally, drainage points should not be within three feet of a public sidewalk and at least 10 feet away from a retaining wall.

K-style gutters are the best option for areas that get heavy rainfall. They look good and can hold more water than half-round and custom-built fascia gutters. The sides of these gutters resemble the letter 'K,' thus the reason for their name.
