The kit consists of bags of chain, hanging rail, fixings and instructions. As additional extras a coloured hanging rail, hanging brackets or ceiling brackets can be added to your order. Measuring When measuring for a door or window chain fly screen, take the opening size and add 2cm (0.75") to the width so the screen overlaps the frame, and add 5cm (2") to the height to account for the hanging rail. The finished size of the screen supplied will be the size requested including the hanging rail. The links are 24mm in length so screens will be +/- 12mm. Installation The brackets that can be purchased separately are 35mm in depth and you need an additional 15mm (50mm in total) clearance above the door/window so that the hanging rail can be hooked over the top. The brackets are supplied with screws to fit to PVC, wooden and metal frames. Ceiling Brackets are also available. Matching coloured screw caps are also provided along with simple installation instructions. We supply all chain products with
