Poly Lock Channel and Spring Wire work together to create the best greenhouse film fastening method on the market.

These 6 ft. pieces of single aluminum channel can be purchased with the associated Spring Wire or without, and are designed to secure Greenhouse Plastic, Insect Screen, Shade Cloth, or Two Layers of Greenhouse Plastic directly to your greenhouse, high tunnel, or hoop house frame, as well as to the front of your end wall.

Simply install the Poly Lock Channel and wiggle the wire back and forth over top the material you are installing and into the channel.
