Polycarbonate Glazing Spring Clips 25/pack
Made from galvanized steel wire, the Polycarbonate Glazing Spring Clips work with glass or polycarbonate, and are designed to be used with almost all aluminum-framed greenhouses.
Heavy gauge wire makes them a little tougher to install, but also to hold better.
Happy with the product but they are a bit overpriced
I bought them to use o missing clips on a Harbor Freight green house kit and they work fine. High shipping cost if you only need one kit, better to use mail maybe?Ben
