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.

Installs in seconds. Simply place both halves around the bung lip, slide the lock bar through the halves and then attach a padlock (9/32" or 7.14mm dia. shackle, typical of a No. 3 Master Lock) through the end hole of the bar. Sold as a pair, these drum locks fit the most popular style of steel and plastic 55 gallon (200L) drums.  The steel set includes two units; one to fit over the 2" NPT plug, the other to fit over the 3/4" NPT plug.The plastic set includes two units which fit over both 2" plugs.
