Works as described
I seen one of my employees using this so I had to grab one though I’ll probably rarely use it. It comes in clutch as I have adjusted doors already with it. I prefer using the wrench method over opening the door. I think if you’re a beginner the method of choice should be the wrench. Make sure you buy a good large wrench for commercial doors. Plenty of videos on YouTube that show how to use it I recommend watching those before attempting and assessing the situation you have as they are all unique and different. If you have an existing closure it may need adjustment as well

Commercial doors sagging this is a must have for your tool box
First time I tried to use it the door hint screws were short and it didn’t work.Beefier hinges and longer screws tool works great…fixed 5 doors not latching in 5 minutes.

Great product, lousy case
Great tool, poor case. Damaged in shipping, I couldn't imagine it would hold up much better in my truck boxes. For the price of the tool they could provide a better case. Just my opinion, still left 5 stars!

works very easily
I ordered this tool after seeing a contractor use it when we called him in to repair one of our sagging doors. After spending much time trying to shim door hinges to stop them from sticking I thought it was worth a try. I received it over the weekend and tried it this morning. It took about 2 minutes and I no longer had a sticky door.

Hinge Doctor
When using this product properly, the hinge Dr. works exactly the way it’s meant. As long as you don’t over force it, it’s worth every penny.
