Prevent drum failure by using these vents to release pressure and vacuum buildup caused by draining liquids and sudden temperature changes. In case of fire, a flame arrester prevents flashback into the drum.
Style D has a removable cap so it can be used as a fill opening.
Style E comes with two carbon filters. The filter traps 99% of vapors.

Drum Locks
Locks for open-head drums replace the standard 5/8"-11 bolt on the closing ring and lock with a padlock (not included).
Padlockable locks for closed-head drums replace the plugs on 3/4" and 2" drum openings. Made of brass, they're non-sparking and resist corrosion in wet environments. Slide the bar through the hole in each plug and lock with a padlock (not included).
