12-Magnet Adjustable Fly Screen

A highly adaptable black fly screen panel, supplied uncut at maximum dimensions of 150 cm × 130 cm. Made from lightweight yet robust polyester mesh with a uniform black dye for consistent appearance and reduced reflectivity. Total unit weight: 320 g. Includes 12 purpose-designed magnets — six flat-mount bases (with self-adhesive 3M VHB backing for steel/iron frames) and six recessed magnetic plates embedded in the screen’s reinforced border. Installation begins with positioning the frame magnets — no drilling, no wall damage. Then, after trimming the screen precisely to your window’s inner or outer reveal, simply align and press the screen onto the magnets. It holds firmly but releases cleanly. Full window operation is preserved: no interference with handles, locks or hinges. Mesh remains flat and taut, even after repeated seasonal use. Designed for real UK homes: works with narrow sash rebates, deep uPVC cavity frames (when metal reinforcement strip is present), and heritage timber windows with steel inserts — verified across hundreds of customer installations.
