Justrite tip-over protection system has all the features of Justrite’s safety funnel, with the addition of a self-closing ball valve and vent adapter. The integral self-closing ball valve threads into a 2-inches drum bung and minimizes vapor emissions as well as preventing spillage if the drum is accidentally tipped over. This makes it ideal for earthquake-prone areas. The system includes a separate brass vent adapter which fits into the 3/4-inches drum bung to provide pressure and vacuum relief for protection against drum rupture or explosion. Measures 10-3/4-inchesdiameter by 10-inches height. FM Approved.
