Strong and reliable plasterboard fixings designed for hanging heavy objects like cabinets, TV brackets, radiators, and boilers. These heavy-duty fixings hold up to 133kg and are suitable for stud walls with plasterboard thickness ranging from 12.5mm to 16mm. The smart wing design deploys behind the plasterboard for a secure hold that won't loosen over time. This starter pack includes 8 extra fixings, 8 screws (5mm x 35mm), and a 20mm drill bit for easy installation in 5 simple steps. A cavity of only 20mm is required. Please note: requires a compatible bracket for radiators (not included) and is not recommended for TV mounts with cantilever or extendable arms.
