100mm bridge and flat packers are stocked in a range of widths and thicknesses. Bridge packers are used to ensure any water entry runs under the purposely made ‘bridge’ and drains through the slot holes in the UPVC frame. Flat packers are ideal for alignment and spacing for when the window is being installed.
