How does it actually work though?
Alright, so the idea is simple enough. Because the jar opener was mounted below the kitchen cabinet – it just lives there, like a part of the cabinetry if you will, but way less obvious.

You would only ever notice it if you looked up and laid down on the floor. This begs the question: why would you be adjusting yourself vertically like that unless you just dropped something? However, once you install it, you really don’t have to think about it. Unless you really need to open a crusty jar that has fought you while you were trying to pry it open – then it actually becomes your best friend!

The getting the thing up
The first part of the task is: locating where you want the thing to go. You can’t just throw it anywhere – it has to be convenient to reach, but also doesn’t get in the way. As an example, you may not want to put it within reach in an area where you lean over to slice onions or something. Then you will want to clean the area – because kitchen grease is subtle, and will land in the most awkward back corner of your cabinets. You would swear to God you’ve never placed food on such spots!

When done to the underside of the cabinet, you will need to mount the thing using screws (if it is new, the screws come with it; if it is used, who knows!). It’s screwed into the bottom of the cabinet – again, you do not want to half-fit it. So just make sure when you take the lid off something it does not wobble off, or rip off. And that’s it. There are no advanced handyman qualifications needed for this job!
