FastCap KNUCKLEBENDER Adjustable Door Hinge Tool with Built-In Hinge Pin Remover – Versatile Door Alignment Solution

This tool seemed expensive/overpriced, but I needed to adjust a steel door in steel frame that had sagged. No good answer, except this tool. It worked like a charm. One of those items that only works for a small number of problems, but when you have that problem you'll be so glad that you have this tool!

What a great tool. Easily does what it says it will do - adjust the knuckle on a door hinge so it closes properly.

The FastCap KNUCKLEBENDER is a super handy tool for tweaking doors without pulling them off the hinges. It’s strong, easy to adjust, and makes quick work of aligning doors that rub or won’t close right.✅ Solid Build: Feels durable and delivers good leverage without damaging the hinge or frame.✅ Easy to Use: Adjustments are straightforward—even works well in tight spots.✅ Saves Time: No need to uninstall doors for minor adjustments. Huge win!Only reason for 4 stars instead of 5: the grip could be a bit more ergonomic for extended use. Still a fantastic addition to any toolbox for carpenters or DIYers. Would definitely buy again!

This is a real neat thing, especially if you are a handyman or fix doors regularly. Had to file off some burr on mine, so the finish wasn’t the best.

Works really well. I have spent countless hours shimming, chiseling, fiddling with hinges to adjust a door to fit. This tool avoids all that extra work. I can "tune" a door to fit in short order. Great idea

The idea is great, and the tool is easy to use. Compared to the other methods of fixing a door that is out of alignment this one is much easier and faster.Unfortunately there are some quality problems with the tool. First, the wrench itself is very cheaply made. Made of poor quality steel - it is easy to bend and break, I have had three of them now - so its not just a quality control problem - it is a lack of overall quality problem.Pull too hard and you will bend the bottom (thin) part of the jaw - rendering the tool useless. The adjustment thumb wheel "kind of" works when new, and if used hard will just jamb.The storage for the hinge pin removal tool is a nice idea, but poorly executed. There is a magnet in a plastic part to hold the hinge pin removal tool in place. Unfortunately the magnet is free to move - and moves into a position that prevents the hinge pin removal tool from being able to be inserted back into the hole.If they started out with a better quality wrench and improved the hinge pin removal tool storage system they would have a nice, useful tool. Of course this would cost a little more, but to me it would be worth it - better than having to buy multiples to have one that works.As it is, it "kind of" works.

Does exactly as advertised. Solved a problem-door situation easily.

What a fantastic tool.It has a good heft to it with a nice build quality. The alignment of some of my interior doors have always been off enough to be annoying each time I used them. Now the reveals are even and they close nice and tight. Just pop the hinge pins with the included push pin and use the tool to adjust the direction of the door hinge.Pros: Well built, fits around hinge tightly so it does not mar or score the hinge surface. Plenty of leverage to easily adjust the hinge sections. Convenient push pin for removing the hinge pins.Cons: Only one and perhaps a bit of a nit. The push pin is a bit loose in the nylon or plastic holder such that it can slide through. It would be helpful if it were more snug fit so it stays in the position you set it.Totally worth the money. I would buy again, but will never need to.
