PRODUCT SPECIFICATIONS

COMPATIBILITY

We've been using these 3x4" downspouts for years on all our residential projects. The quality is consistently excellent, and the wide range of color options allows us to perfectly match any home exterior. These are our go-to downspouts for reliable performance.

As a contractor who installs gutters on both new construction and renovation projects, I need products that are reliable and easy to work with. These 3x4" downspouts meet all my requirements - they're well-made, consistent in quality, and the powder coating holds up extremely well over time.

My gutter installation business has been using these 3x4" downspouts exclusively for the past five years. The quality is consistently excellent, and my customers appreciate the wide range of color options. The 10ft sections are perfect for our local jobs, while the 8ft sections work great for our out-of-town projects.

Q: What is the difference between 8ft and 10ft sections?

A: Both 8ft and 10ft sections are identical in material, construction, and quality. The primary differences are length and shipping availability. The 10ft sections provide fewer seams in your installation but are only available for local delivery or pickup due to shipping carrier restrictions. The 8ft sections are available for nationwide shipping, making them accessible to customers outside our local delivery area.

Q: How many downspouts do I need for my project?

A: As a general rule, install one downspout for every 30-40 feet of gutter. For areas with heavy rainfall or large roof surfaces, we recommend increasing to one downspout every 20-30 feet. For the most accurate assessment, consider the roof area being drained, local rainfall intensity, and the slope of your gutters. Our professional team can help you calculate the optimal number of downspouts for your specific project.

Q: What brackets should I use with these 3x4" downspouts?

A: These downspouts require standard 3x4" rectangular downspout brackets. We offer compatible brackets in matching colors, sold separately. For optimal support, install brackets approximately every 3 feet along the downspout and within 12 inches of any elbow or transition. Our brackets are designed specifically for professional installation and long-term durability.

Q: How do I cut the downspout to the length I need?

A: Rectangular downspouts can be cut using tin snips (for straight cuts) or a power saw with a metal-cutting blade (for longer cuts). For best results, measure carefully and mark your cut line around the entire perimeter. After cutting, use a file to smooth any sharp edges before installation. When using power tools, always wear appropriate safety equipment including eye protection and gloves.

Q: Why are 10ft sections only available for local pickup or delivery?

A: Due to shipping carrier restrictions and the risk of damage during transit, 10ft downspout sections are only available for local delivery or pickup. The longer length makes these sections difficult to ship without bending or damage. For customers outside our local delivery area, we offer 8ft sections that can be safely shipped nationwide while maintaining product quality and integrity.
