Bought the GearTie Original 32 inch x 2 pack at Lowes and cut them into 2.5 inch lengths to attach shade cloth to the interior of my FarmTek 12 x 16 greenhouse. They fit perfectly into the rail slots (where the bolts usually go) and the ribbed outside and wire interior made them hold fast. I can pull on the shade cloth and they pop right out when I want to roll back the shade cloth. No more problems with wind, tears , sagging or using bolts to hold the cloth in place. Will buy more for their intended use too.
