Got a stuck lid on your Fermonster? Get it open much easier with this specially designed lid opener. It easily slides onto the lid and gives you comfortable hand grips to open a stuck lid.

Note: We do not recommend using this tool to tighten the lid because the seal is made by the o-ring and not the pressure between the lid and neck.

Can this key be used for fermentassaurus?
BEST ANSWER: The grooves in the lid opener are designed to match up specifically with the grooves of the Fermonster lid, and will not work with the fermentasaurus lid.

Glad I have it
This may not seem important but if you use Fermonster carboys then eventually you'll screw a lid on too tight and this will come in handy.

Works great
I wish I was burly enough to open the FerMonster without this guy, but it does the job perfectly. Very happy I went ahead and grabbed one.

Not required, but definitely helps!
For a couple extra bucks, I decided to buy this when I got my 3 gallon ported Fermonster. I was not sure if it'd be worth it. But it turned out to be very helpful.

The indents in this opener fit in the grooves on the Fermonster lid, making it very easy to open the Fermonster even after fermenting. I'm guessing the pressure changes during fermentation which can create a bit of a vacuum and make it difficult to take off the lid. This solves it.

It's cheap and helpful. Good buy in my book.

Great tool
Amazing how the Fermonster lids are impossible to remove. Doesn't matter if I put a small amount of keg lube on the gasket before using the lid, when it's time to remove the lid, the lid will not come off.

Enter this tool. Makes it easy to remove a stubborn Fermonster lid.

Works - but breaks lids
Don't use this to try an tighten down the lids. You'll crack the lids. If you're having sealing issues, put the lid on the container while it's upside down. That seems to do the best to prevent the o-ring from popping out.Of course - this requires the container to be empty.

Only use this to remove the caps.

I’m glad this was added to this mfg products. The lid can be difficult to remove by hand particularly if any sweet juice is on the seal.
