Calculated Industries 1194 Air Shim XL Inflatable Pry Bar and Leveling Tool; 500 LB Load Holding Rating; Contractor-Grade Alignment Pump Wedge

I use this to tilt my freeze dryer back to get the excess water out after I shut it off. This works great.

I used this air pump to re-level a 50 gallon rimless aquarium that I had spent 6 months aquascaping, gluing pieces of rocks together, among other things that caused it to go off-balance again. Needless to say, I couldn’t just empty the tank to re-level it, so I had to find something that could lift a lot of weight and do it smoothly.I estimated this tank to be approximately 600 lbs+ filled. I was planning on emptying 3/4 of the tank to fix the level, but due to shrimp getting stranded in the higher portions of the scape, I could not empty more than about 40-50% of the water.I was nervous because I had experienced a cracked tank in the past and did not want a repeat! I needed something that could hold the corner of the stand up, but do it smoothly, not to slosh the water and cause more strain on the glass. I’m relieved to say that the process was actually pretty easy!The first picture is of the tank, the second two pictures show the level being off just the wrong amount. The last 3 show a perfect leveling of all sides after the job was completed. (I didn’t include a picture of the back glass, but it is just as perfect).The only regret I have is that I didn’t have this tool back when I was trying to level the stand at the start. The stand comes with screws underneath that allow you to level it, but nothing to hold the corners up while you’re doing the leveling. It would be nice if this air pump was came with a wedge like some of the other brands, but fortunately the flattened bag was easy to slip into the slightly less than 1.5” gap under the stand. I accidentally knocked off the pumping once, but this did not cause the air to release from the bag and it was easy to put back on, so I suspect this is part of the design. The air released gradually and smoothly when pushing the air release button. All in all I highly recommend this air pump!

Excellent product

I bought this to help adjust my closet door because it was not closing shut. I didn't have a wedge high enough because there's a 1.5" gap from the door to the floor. I placed this shim underneath the door to help put the door in its correct place so I can adjust the hinge. This made it so much easier and doesn't require someone else to hold the door in place while I adjust the hinge. My only gripe about this item is that the pump hose is way too short. If it was longer, I would have given this 5 stars for sure. It was easy to use and the air release worked well.

This is one of those tools you need in the tool bag. Bought it on Prime Days and I am more than impressed. Slide it under a heavy 150 lb solid wood door and with my foot could pump it and lift the door 1.5 inches up to hinge it. Turned a two man job into one. Lifted a heavy 200 lb desk up on one side to put carpet savers under the feet. In 5 days I have used it over a dozen times from doors to desks to windows and has saved time and man power, lifting things just an inch or so for making things plum or getting on hinges etc. etc. a must have tool.

It's like having an extra hand. I purchased to raise up the refrigerator so I could level it, it worked great.

Worked as it should, but funky awkward configuration. It would be much more convenient if they hold was perpendicular to the bag
