This set of triple jump cups is designed to fit securely on the lip of 205lt oil drums. It can reach heights of 97cm, 71cm and 46cm respectively, thanks to its red stubbyfine coated steel construction and one piece steel construction (zinc plated). The cups easily hook on and slide off, and measure 54cm in height, 14cm in width, and 10cm in depth. A spare bracket is also available for purchase, but please note the red bars connected to the jump cups do not come with the spare bracket; you will just receive the gold spare bracket.
