Justrite drum locks are a cost effective solution to controlling storage concerns of all types of liquids, semi-liquids, and powders that come in standard drums. Made of corrosion resistant, non-sparking zinc die cast, the units easily install around the drum bung flange with no risk of cross threading. To secure the drum lock it is not necessary to remove the original bung, therefore there is no contact with the drum contents. This elimination of potential content contamination has applications across many industries, including chemical and food processing.
