The narrow-backed staples fit staplers from the following brands: AEG, Bosch, Black+Decker, Bukama, Esco, kwb, Metabo, Novus and Wolfcraft. The narrow-backed staples type 55 are plastic-coated to achieve an adhesive effect that provides a strong and long-lasting hold in a range of different materials. This makes them ideal for both DIY tasks and professional purposes such as installing wall and ceiling cladding with joint and profile board brackets. The staples also have a narrow back that allows them to penetrate deeply into the material and provide a good hold with a very discreet staple back. They are particularly suitable for stapling thin materials where the staple back must not be pressed into the material
