## Questions & Answers

**Q: I saw some bad reviews.  Is this product the real deal now?  As in does it look like the picture shown and does it work?**
A: I purchased one just a few weeks ago and within five minutes of opening the package I fixed an entry door that was driving us nuts! Yes, it works just as demonstrated in the FastCap YouTube video.

**Q: I'm seeing two images for this tool. Is it a wrench type of tool for the door hinge?**
A: I'm not sure if you mean two separate tools or a tool that can do more than one thing.  One end has a long metal rod that helps to push out door hinge pins. The other end looks much like a wrench but has  an adjustable "clamp" is made specifically to fit around a door hinge. There's a great How-to video on it's use on YouTube done by See Jane Drill.  I used it on two different types of doors, one with vintage hinges and the other with modern day hinges; in both instances it worked like a charm. I'd never worked on door hinges before. It's a great tool.

**Q: My door is sticking on the top of the door frame on the strike plate side.  Which way do I bend the knuckles on the door and  the door frame hinge?**
A: look up.     how to fix a sagging door      ======see Jane drill==========   YouTube

**Q: What's the difference between this and a regular adjustable wrench? Wouldn't an either do just about the same thing? Look at the pics. They made one!**
A: Zoom in on the front of the jaw. You could take an adjustable wrench and do some grinding and make your own if you’re a good fabricator. But it’s really not the different.

### ⭐⭐⭐⭐ Good tool but not great
*by R***S on January 3, 2026*

This is a worthwhile tool but it could be a bit longer to increase the leverage. If you fix a lot of doors buy it.
