Polyfastener or Cinchstrap?
Choose Polyfastener for places where you want to open & re-close the poly. Generally used on perimeters only. The sheet of poly must come out from the wide-lip side. If used as a seam, be sure both pieces of poly come out from the wide-lip side. One piece then crosses over the Polyfastener to go back to the direction you want.
Choose Cinchstrap for places where you want to nail poly on and leave it there until replacement time or for a clean white inexpensive sliver-free lath for any project large or small. Most smaller greenhouses use cinchstrap or some use a combination of polyfastener and cinchstrap.[an error occurred while processing this directive] [an error occurred while processing this directive]
