Our offsets are designed to be used to get a downspout over a brick ledge, pipe, or other protrusions that are approximately 4” in size. Offsets can also be used as a header when the overhang allows. Our offsets are a 2-piece unit with one standard 45-degree A-style elbow and one 45-degree A-style elbow with a lengthened leg to complete the desired offset size. All offsets are manufactured from .019 gauge aluminum and available in 2×3 and 3×4 sizes. All elbows come individually wrapped in polybags to help protect the elbows.
