Theft-Resistant LP-Gas Cylinders

Make your own LP-gas cylinder locks

After hearing a fellow RVer’s tale of having the LP-gas cylinders stolen while his trailer was in storage, I decided to secure my trailer’s twin cylinders. I simply drilled matching holes in the large wing nut and the notched crossbar that holds the cylinders. After inserting a padlock through both holes, the cylinders are secure. I used a lock I had on hand for my garden shed, but the 3½-inch-long (89 millimeter) Trailer Coupler Latch Lock (1471DAT) from Master Lock would work well.

  1. Locking propane tanks in place can be a very dangerous practice. I have seen what happens firsthand when a propane tank explodes during a fire! In the event of a fire, if at all possible, propane tanks need to be quickly removed and taken to a safe place. Not doing so can endanger lives.

  2. The drawing shows a regular nut, which is not shown as part of the “wing nut bar” in the drawing with the drill. Of course, that implies the nut could be separately removed from the assembly, making the lock completely useless. The reason this method works is because the nut is welded to the wing nut bar and the lock keeps the wing nut bar from turning. Good idea, silly illustration.

  3. Yes, that works well! I did that when I went from 20- to 30-gallon tanks, but had to get a longer threaded rod to accommodate the taller tanks. Works great!
