Common Applications
Installation Guide
- Measure the offset gap — confirm 2" clearance is required between the fascia wall and the downspout centerline.
- Mark and cut the existing downspout — use tin snips to create a clean square cut at the connection point.
- Slip the extension onto the downspout — the wider end slides over the existing downspout with a secure friction fit.
- Align the offset direction — rotate the extension so the 2" displacement points away from the wall surface.
- Secure with rivets or sheet metal screws — drive two fasteners through the overlap on each side.
- Seal if needed — apply gutter sealant inside the joint for wet climates or high-flow applications.
- Check alignment — confirm the offset is plumb and the lower downspout section aligns correctly before final fastening.

Why GutterAll
Customer Reviews
"Clean fit on my 3x4 system. The 2-inch offset was exactly what I needed to clear the stone veneer on the corner. Color match was perfect in Musket Brown."
"Solid aluminum construction, not the thin stamped material you see at big-box stores. Held up through our wet Oregon winter without any leaks."
"Ordered 6 in White for a new build. Fast shipping and all pieces were identical — no color variation. Would buy again."
Frequently Asked Questions
What makes the Double A Offset design superior?
The Double A configuration uses two precision bends to achieve a smooth 2-inch displacement while maintaining full water velocity. The dual-angle design eliminates sharp direction changes that cause turbulence, debris buildup, and premature wear.
Will this fit my existing 3x4" downspout system?
Yes. This extension is engineered specifically for standard 3x4" rectangular downspout systems and provides a secure, leak-free slip fit compatible with all major manufacturers.

GutterAll offers 25+ designer colors. Contact us at sales@gutterall.com or call (503) 496-7017 for color samples. Local Damascus customers can visit our showroom for in-person matching at 19759 SE Sunnyside Rd.
Can I install this myself?
Experienced DIYers can complete installation with standard hand tools. Slip the extension onto the existing downspout, align the offset direction, and secure with rivets or screws. Professional installation is recommended when working at height.
