1-3/4" Hidden Hinge Stainless Steel 180 Degree Invisible Cross Hinges for Kitchen Cabinet Door Frameless Concealed Hinge with Screws, 4pcs

These are nice hinges. I used them for a display panel with folding wings. They're well made and worked well.

Got my hands on these Rierdge Hidden Hinges for a countertop project I was working on, and they’ve been pretty solid. They're the 2-3/8" stainless steel type, and I grabbed a 4-pack. So, the cool part? They’re totally invisible when everything is closed up. Gives everything a neat and tidy look, which I’m all about. They open up all the way to 180 degrees, so no issues there getting to what I need. The material seems decent. It’s stainless steel and feels sturdy enough. They threw in the screws too, which is always a nice touch, and it wasn’t a hassle to install them. Size-wise, they’re not too big and not too small. Checked the dimensions before buying, and they fit just right for my project. Each hinge is supposed to carry around 10kg, and so far, no issues with the weight. You can pretty much use these for any wood or metal gig—closet doors, cabinets, you name it. I’ve only tried them on my countertop project, but I can see them working well for other stuff too. All in all, not a bad buy. They do the job, look clean, and seem like they’ll hold up. If you’re into DIY and need something that’s out of sight when your project’s all closed up, these could be worth a shot.

Works great

Somewhat difficult to fit without a jig.

These are perfect for my outside bar. Installion was a breeze. They are very sturdy. Great value for the money.
