Randy: Hey guys. Randy here at etrailer.com. Today we're taking a look at a new product from Torque Lift. It's the Fortress gas lot. This is going to give us an excellent solution that we really haven't had in the past. This allows us to lock two propane tanks down to the front of our camper or RV, and prevent them from being removed.
Now, not only does it secure our tanks as you can see, but also our regulator, and also our hoses. So we're not going to have to worry about all of those pieces disappearing causing us a very expensive replacement. Whether you've got the half inch, or three eighths inch threaded rod, we're going to have a solution for you. It's going to have a heavy powder coat finish on it, and it is lightweight. It's made out of military grade aluminum.
So we're not going to really have to worry about any corrosion, or any issues like that. Also, going to have our lock right here. Nice heavy duty lock. Pull that off and see we've got our cap open there.That'll allow us to slide our key in there, lock and unlock that, and then back this off if we want to get our tanks off to take them and have them filled or whatever we might need to do. Now to install our Fortress lock, we'll need to remove the old style wing nut.
Just going to loosen that up and set it aside. Then we can bring our Fortress lock right down and over. I'm going to position this tab rearward. Since our regulator is right here, I want to have enough room for my lock. Now we'll take that stainless washer.
We want to place that down on. Then we can get that threaded down and on. Now, we're going attention this just like we would our normal keeper here. We just need to ensure either this tab or this tab lines up with the tab on that lower section, so we can get our lock through.So right there looks good. Then we can place the lock through. We have the option of placing it either way we want. I do recommend though that we put this rubber spacer on the top side. We can put our lock on this way. But as that goes down the road, that'll kind of keep it from rattling. We won't hear that metal noise as it bounces up and down. We just put our cap on. But at that point, everything's going to be nice and secure and we won't have to worry about anybody getting away with our tanks. That's going to complete our look at the Fortress gas lock from Torque Lift.

Timely delivery. Easy installation.
One note: Raising the regulator caused interference with slam latch. Had to bend bracket as shown in photo. Otherwise good product.
Might be good on some trailers but it did not work on my Grand Design. See photo. Could not get it pushed down far enough to put padlock on before the end potecting the nuts jamed against the upright threaded stock.
Very easy to use and perfect for what it is intended for. Came earlier than expected and good quality. Just make sure you measure correctly not like me, and order the correct size. etrailer customer service was great on helping me return the wrong size and ordering the right one.
Thanks
Good product and good service
Peace of mind
Well made product overall. For what you pay you would expect a beefier lock. Best option out there.
without a doubt a wise investment. Not only is the connection simple and easy (never getting bayonet tolerances making for a touch connection to twist in place - or untwist), but the hose itself is the most durable I have used.
Great customer service and knowledgeable on the products they sell.
This is the perfect accessory for our new Airstream! Will keep the propane thieves at bay! Thanks etrailer!!
Great product. Simple to use and well constructed. Prompt shipping and delivery by Etrailer. Thanks.
Installed the lock today. It works as advertised and is pretty much the only LP tank lock that works well on an Airstream trailer. The instructions show installation with the barrel of the keylock in an upwards position, however, my Airstream trailer has large 40 gallon tanks and the cover brace is raised rather than dipped. The keylock barrel must be installed in the downward position or it won't fit beneath the plastic top cover. This makes is slightly awkward to insert the key, but it also makes it nearly impossible to drill the locking mechanism out. The lock is easy to install and easy to remove when needed.
A great tank locking mechanism to help stop the storage lot thieves .
Fit perfectly bit lock has to be installed lock side down for Airstream tank cover to close.
Works great! Ive owned it one year now and no corrosion issues. As long as somebody can't undo the gas rod from the bottom, then the lock is secure against theft. It would be very cool if this product had a model that used a 4-digit combo lock instead of a key (I often misplace my key, but started keeping the key inside the Airstream

Its been a year and the lock has performed just fine. It is kept out of the elements under the propane tank cover, but I do live by the beach and there is no evidence of corrosion from the salty air. Good product!
Installation was easy for both products.
I used this GasLock Kit on a trip to Alaska and when we got home there was absolutely no wear or tear on this kit. This product secures the tanks to the trailer with the peace of mind that those tanks will be there when you get back.

Glad these kept everything safe on your trip, Pierre! What kind of travel plans are you cooking up for next?
Excellent design! Easy installation on 2019 Airstream Globetrotter 27FBT. Now my LPG tanks are secure.
I ordered 4 Mighty Cords and a TorkLift gas bottle lock for my Airstream. The cords were nice and recommended by the AS forum. I rodered the wrong TorkLift for my AS. I needed the 1/2" lock assembly but ordered the 3/8" by mistake. etrailer responded and sent me the correct TorkLift and a return merchandise mailing label! Thanks! Nice people to do business with. Here is the TorkLift installed on my AS.
Make sure you measure your threads before ordering!
Outstanding product. like that it is aluminum construction so it wont rust. The lock is crap, I replaced with a standard outdoor rated padlock. This is the 1/2"-13 thread. Need to pay attention to thread size when ordering these.
Works like a charm. Perfect fit for my Airstream International with 1/2 inch fitting. Before ordering check if your Airstream is 3/8 or 1/2 fitting.

It works great. Still the only problem is that the lock has to be turned upside down for the lid to close on propane tanks. Not a big problem but should be corrected by new generation of the lock.
