Invisible Hinge

These are excellent very strong hinges.However, you do need a template to install.I used a template from MinnPrint on Etsy and it made install a breeze!

Used these to build a hidden door in my basement. I'm so surprised at how smooth and solid these hinges are. The door I built is massive, and heavy. I'd say it weighs about 100 lbs and I only used 2 of these. I've been opening and closing the door at least a half dozen times a day and it hasn't sagged or done anything weird at all. It's handling it like the door is weightless. Incredible. So happy I found these. Extremely high quality product that is worth every penny.

Used on a bookcase door and it worked great. Very heavy duty. Make sure the thickness of material you are installing on is deep enough it’s a very deep unit.

Installed only 2 on a hideaway cabinet on rollers. Does a fantastic job on big wide custom built cabinet. Super happy and easy to install. I am a professional trim carpenter so was very easy to router and drill out holes to line up the hinges.

These are really heavy duty. I didn't expect nearly the weight these have. Once installed, they look great. But, the key is probably an experienced installer. Frankly, you need to modify the door jam for heavier doors (i used four on a solid ~1.85" fire door to garage) if you are going flush without trim. This may be because the hinge sits so close to the edge of the jamb/wall and are so recessed that on the opening side you aren't bolting into anything... you're facing the side of the drywall up against your jamb (hence the need to modify). I'm just a weekend warrior when it comes to handy craft, but I found a lot of lessons necessary to get this just right. And if you are going to drop over $100 on hinges per door, you want them right. I'm sure internal doors (and of course cabinetry) are easier.

This is the only thing that works for my floor mounted door for access to crawlspace equipment. The door is in a tiled floor and very thick and not having hinges sticking up tripping me was very important. So far these are working well on the door with 150 lb hydraulic arms pulling on them.TIP: have a very sharp chisel to get these embedded perfectly

We have an upstairs landing in our house that is door-heavy: 3 bedrooms and a laundry room.We wanted to conceal the French-doors of the laundry room and make it look like the wall so that the landing didn’t seem so crowded with doorways.These hinges definitely did the trick. While I wasn’t totally satisfied with how well the laundry doors blended into the wall, that had more to do with my contractor than with these hinges. Properly installed, the doors work smoothly without visible external hinges.Just be sure to order the quantity you need - I had assumed each order was 4 hinges but it is not. I was a little surprised by the price, and wish they were a little cheaper, but since we only needed them for that one door, it was okay.

made a hidden passageway in myhouse. I used a bore bit and made the openings the hard way. In hindsight i would buy a jig and do it the right way. There’s not a lot of room for error with these. It took me a long time and a lot of aggravation getting them in. But in the end it was worth it.My door has gotta be 150-200 pounds. 3of them hold it up no problem and the door swings smooth with no creaks. Really smooth.
