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 come with the associated Spring Wire, and are designed to secure Greenhouse Plastic, Insect Screen, Shade Cloth, or Two Layers of Greenhouse Plastic directly to your greenhouse hoop frame or 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. 

Unlike using wooden batten strips to secure greenhouse coverings, Poly Lock and Spring Wire hold the plastic in place without requiring holes be drilled through the plastic itself to secure.
