FSD Bifold Door Black Lip Flipper Weather Rubber Gasket Seal 6Mtr AF612. Fitting tip: gasket can be neatly cut to size with sharp household scissors. When fitting for best weather performance it is best to start in the middle of the top rail at the top of the door or window as this is normally the least area of water penetration and driving winds so that the bottom of the door or window system is always in one continuous piece.
