Repurposed an old 10'x20' canopy carport into a greenhouse for the garden. After watching a number of YouTube videos, this looked like a good way to "permanently" attach the plastic to the frame. I added some other stiffeners and cross-frames to stiffen up the frame a bit, then attached these strips to the frame. It's nice they included self-tapping screws, but I would recommend predrilling the holes to ensure the screws go where you want.Once installed, easy to attach the plastic using the zig-zap strips. Just be careful with any sharp edges that may inadvertently cut your plastic sheeting. These provide a great method for attaching the plastic sheeting, without having to worry about it coming free in the wind.
