Common Applications
Route downspouts around porch and entry columns without cutting or removing architectural elements.
Navigate past window sills and brick ledges with a clean professional offset that stays tight to the wall.
Offset the discharge point away from foundation shrubs and plantings for improved drainage positioning.
Move discharge location laterally to reach a drain inlet, splash block, or underground drainage connection.
Installation Guide
- Measure the offset: Mark the obstacle on the downspout run and confirm the 6" offset will clear it on both sides.
- Cut the downspout: Cut the existing downspout section to the appropriate length, allowing for the elbow's height of approximately 13".
- Crimp the male end of the upper downspout section so it slides into the female end of the top elbow opening.
- Slide and secure the elbow: Slide the top of the elbow onto the upper downspout and secure with a sheet metal screw through the outside edge.
- Connect the lower section: Slide the male end of the lower downspout into the bottom of the elbow, crimp if needed, and secure.
- Check alignment: Confirm the lower downspout is plumb and the offset clears the obstacle. Caulk seams if required by local code.
Safety Notice: Installation requires working at height. Use a stable ladder, non-slip footwear, and follow OSHA ladder safety guidelines. Professional installation is recommended for two-story and commercial applications.

Customer Reviews
4.8 out of 5 — 27 reviews
Perfect fit for navigating around a stone column on our house. The 6" offset cleared the obstacle exactly as needed. Aluminum quality is excellent and the white color matched our existing system perfectly.
Used the musket brown on a cedar-sided home. The color is a great match and the double-A design makes installation straightforward. Ordered several and picked up same day in Damascus.
Contractor here - ordered black elbows for a commercial project. These are the real .019 gauge, not the light stamped stuff from the big box stores. Exactly what I needed at a fair price.
Frequently Asked Questions
What is a Double A Offset downspout elbow?
A Double A Offset uses two 45-degree bends to create a 6" lateral offset in your downspout run. This allows the downspout to navigate architectural features such as columns, sill projections, and foundation plantings while maintaining a straight vertical run and proper water flow.
Will this fit my existing 3x4 downspout system?
Yes, engineered for standard 3x4" rectangular downspout systems. The female end slip-fits over a standard 3x4 downspout. Some installations may require crimping the male end for a tight connection. Professional installation is recommended for best results.
