To ensure the highest quality components for every component of your canopy structure, we manufacture every fitting ourselves. We use only high grade galvanized steel to make the 1 7/8" high peak corner end fitting, with welded connections and eyebolts to enable a secure and stable fit. The fitting's inner diameter is 2" and it makes a 120-degree angle for your high peak roof structure, suitable to withstand the snowiest winter, and provide shade and storage in any climate.
