About Noise, Filtration, and Flow Ratings

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).

Keyed locks for closed-head drums fit over standard drum plugs and caps. Use the included keys to secure.

Lockable Breather Vents with Cap

Secure access to vented openings in pipe and tanks—the cap can be locked to prevent tampering. These breather vents allow you to add a filling port to your hydraulic tank while protecting against excess pressure and vacuum. Use them to stop debris from entering your tank. Breather vents mount on top of standard tank openings with included hardware. Padlock is not included.
