The LA 25 27 plug with accessory by Bossong is an expansion fixing system in galvanised steel, designed for light-duty applications on substrates such as concrete, brick and plasterboard. Fitted with a closed eye and integrated washer, it allows a secure anchorage and quick installation, ideal for mounting lamps, pictures and shelving. Its availability in M4 and M5 threads makes it versatile for different fixing needs in building and furnishing.
