Designed for Standard 18' x 20' Canopy Frames
This canopy replacement cover is designed to fit most standard 18' x 20' pole canopy frames. The cover sits on top of the frame with straight edges, leaving a small 3–4 inch perimeter gap between the frame poles and the tarp edge. This design allows water to drain properly and helps prevent pooling during heavy rain.
Like most tarp products, the finished size may measure approximately 6 inches or up to 3% smaller than the listed dimensions to allow proper tension when installed.
