10 x Brown 25mm Thick Polycarbonate Sheet Fixing Buttons to fix or Screw into Noggin Purlin rafters or Poly

About this item

• •10 x 25mm Brown Polycarbonate Fixing Buttons
• •Keep your 25mm polycarbonate fixed in one place!
• •These high quality Polycarbonate Fixing buttons from Living Space are designed to help secure your polycarbonate sheets in place. In windy conditions they reduce the risk of the sheet being dislodged. When installed correctly allow movement caused by natural expansion and contraction.
• •Each bag of 10 fixing buttons contains 10 buttons, 10 screw-hole covers, 10 screws and 10 foam compression gaskets. The foam compression gaskets are designed to stop water from getting into the hole where the screw fixes the polycarbonate sheet. They also allow for a small amount of movement of the polycarbonate sheet due to natural expansion and contraction of the sheet. Polycarbonate sheets can expand and contract quite considerably. The compression gaskets also stop uplift due to wind and sheets being dislodged by snow or wind by being pulled out of cappings. Features & Benefits
