"After seeing a demonstration on one of their own sagging doors, they ordered two Hinge Doctor® tools, sent one to their Hayward facility, where they tested it again and ordered six more."

I just wanted to say thank you for the great customer service that GKL offers. I am an institutional lock smith and purchased a mega screw driver a few years ago and quickly realized the benefits. It has made my job much easier. I honestly don’t know how I would get a long without it. The first one I bought magically grew legs and walked away. It didn’t take long for me to miss having it and order a new one. It’s a must have for any institutional lock smith.

Thanks again

I work at a large university and a couple of years ago I purchased a mega screwdriver from GKL and it paid for itself right away. I didn’t realize how important that tool was until it grew legs and walked away. Just purchased my second one and can’t wait to get it. It’s a must have for any institutional lock smith.

Thank you very much GKL!

Our customers from West Virginia University tell the story best.

"We recently bought a set of four of your Hinge Doctors® for our Locksmith Shop at West Virginia University. Normally in the course of a year we have to shim hinges, shave doors and doorways to make them fit. Since we received your Hinge Doctors® we have fixed several doors that, frankly, we figured we would have to remount or plane wood or metal from to get them to fit properly. Today we had a door that was rubbing on the floor at the bottom hinge end of the door and rubbing on the top edge farthest from the top hinge. We carefully used the Hinge Doctor® on the top hinge first and slightly on the other two hinges making the door easily close with the door closer mechanism. Your invention is the neatest thing since sliced bread for us. We have a full set in three of our Carpenter/Locksmith trucks now. The Hinge Doctor® is a great tool. We would have had to spend hours and a crew of several men to achieve what we did with the Hinge Doctor® in about 5 minutes."

"When I was first contacted by Steve about the possibility of a tool that would correct the damage done by someone 'chocking' the door, I was very excited. When I was told that the tool would fit in my toolbox, the hair on the back of my neck stood up. This was going to be a miracle tool if it would work as advertised. It certainly does. I may very well be the person who has used the HA1 and the HA3 the most in this country. There were days that I didn't even bother putting those tools back in my toolbox, they were used so often. I would recommend these tools to anyone that regularly works on doors."

Steve, I used the “Hinge Doctor®” hinge adjuster tool the first week that I received it and it worked better than I thought possible.

Thanks

I used your “Hinge Doctor®” tool was pretty impressed with it, it does just what it claims to do and it's made of quality material. Great invention, Steve.

Steve, I got one of your “Hinge Doctor®” tools and have used it a couple of times. It worked great with hardly any effort. The tool looks good, works well, easy to use, and even if it only worked 50 times it would have still paid for itself. Thanks for a great product.

Steve, I used to remove the hinges from the door and put them in a vise to bend them back to their original condition. Now I use the “Hinge Doctor®” and what used to take up to an hour takes only a few seconds. Thanks for a great tool.

Steve, this (“the Hinge Doctor®”) is a great tool!

I was at a job site yesterday where they had just installed a new 8' tall door with 4 hinges. They could not get the door opened it was so tight. The guy who took me to the door dropped me off and then left me there alone. I pulled my hinge tool out of my bag and crimped each hinge a few times giving me a full 1/8" clearance on the latch side. The door worked perfectly. If you are around commercial door problems at all, this tool is a must for your tool bag.

Steve, I received the new HA3 hinge tool, the tool looks great. I was amazed. It does a good job and saves valuable time. Thanks, and keep up the good work.

Hello Steve,

After buying several hinge tools and testing them out, I am pleased to say they work great, and are a much needed product. As we discussed, I teach several classes of ALOA and other associations, and would be happy to demonstrate the tool in my classes. I will give out your phone number and e-mail address. Also please send me some information on your other tools, jigs etc., as I also do a class on Door Closers, and exit Devices.

Thanks again, the tool is very impressive.

After seeing a demonstration on one of their own sagging doors we ordered 2 hinge tools, sent one to our Hayward Ca. facility where they tested it again and ordered 6 more.

I used my “hinge Doctor®” twice in the last week. It really impressed my customers that a 'little girl' like myself could repair a big ol' steel door all by myself! I never let them see my secret weapon, I let them assume that I had to take the door down and do all sorts of work to it! :) Thanks to whoever it was that came up with such a great tool!

I had a call today to put locks on some inner office doors at an old warehouse facility. I notice upon entering the building that I had to use both hands to pull the door open and then it wouldn't shut behind me. I tell the guy I can fix it and ask if he'd like me to do it and add it to the P.O. He tells me there is no way to fix it because all the MEN working there had already tried and it was unfixable. I told him to at least let me try. He hung over my shoulder during the entire call so I put the hinge off till last. He finally had to go talk to some guy across the warehouse so I made my move. Whooped out my Hinge Doctor®, and within 10 seconds, had a perfectly aligned door. When I got ready to leave, the guy says, "Did you change your mind about fixing our door?" I said, "I already fixed it, check it out." I bet he's still scratching his head over that one!!!!!!!!

I Used it again today. I just can't say enough about this tool (The Hinge Doctor®)!!!!!!!

I purchased this tool 4 or 5 months ago and it has paid for itself many times over. This is the new Locksmith secret weapon, simple and effective. The only problem is now I need to change my hourly rate to a flat rate.

Lance Edwards

I have used the hinge doctor® and find that it is a must have tool in your tool box. Well worth the price of the tool. It can easily pay for itself in at least the second time you use it.

Rod Springfield

I've had the opportunity to use my new Hinge Doctor® tools a few times. This tool is worth it's weight in gold. It's unbelievably simple to use and the results are phenomenal. If you have not yet purchased these tools, you must.

The last door I used it on it raised the latch side of the door almost a full half an inch, in seconds. It looks like from now on the only time I'll have to install reinforcing pivots is when the hinge plates are tearing loose.

And I don't know what you other guys with these tools are charging but I'm charging 45.00 per door. And just because a door is not yet rubbing the frame or missing the strike, if you will point out the fact that it is sagging you can probably get the OK to fix these doors too.

I love these tools!

PS Try not to let the customer see how you fix the door. They might get miffed at how simple and quick you can fix the door in relation to what you charge to fix it.

Well, I am just so excited about these tools I just had to share.

Thanks,

Steve Craiger

I just got a set and used them on some Outside School doors and they are as you say GREAT .

Just got back from drilling the stainless doors. Thanks to all of the advice & tips the job went great, and I have picked up a new client. I also did some door tweaking with my hinge doctor®, the owner couldn't believe that the doors worked so well, they hadn't closed properly in years.
