From the humble beginnings of the knock box, (basically a box with a bolt fitted into it) this design is something to really show off.
The knock box consists of a round stainless steel tub with the raised back acting as a splash guard. Added features include a protective rubber gasket and it’s neatly finished with a non slip base that helps cushion the impact on your wrists and deadens the sound. Each box comes with a spare rubber bars.
