Plasplugs Hollow Door Fixings Pack of 5 are specially designed fixing plugs for securely attaching items to hollow doors and thin panel materials where conventional wall plugs are unsuitable. Ideal for installing coat hooks, name plates and other lightweight fittings, these compact hollow door fixings use an expanding wing design. As the screw is tightened, the wings expand and grip behind the facing surface, helping create a secure fixing within the hollow construction. The fixings feature multi-thread technology for improved holding power and can be used with hollow doors, thin-skin partitions, plywood and fibreglass. Their versatile design makes them suitable for fixing applications around the home as well as in boats and caravans.
