Ball knobs are used as an ergonomic operating part on hoods, flaps and doors and their round shape reduces the risk of collision. Small dimensions can be fitted on the end of threads to round off edges and prevent injury.
The ball knobs are available in a wide range of models and materials. For example aluminium, stainless steel, thermoplastic or duroplastic. They are also models available with threaded inserts, clamping sleeves or boreholes.
