So far so good! The 180 degree snap-in functionality works really well! But I have four of these per one bifold door.

Muy buen producto cumple totalmente

I love the look of these but the hinge pins were to loose to provide a stable hinge side to side. I couldn't use them for my project.

I kept seeing that they didn't lock at 90° but I didn't care because I needed them to lock at 180° THESE DON'T LOCK AT ALL... spare yourself the headache of returning them. They don't work! The traditional slide hooked bar ones are amazing though. Glad I bought them at the same time so I could complete my DIY project.

These worked perfectly fixed my problem and so easy to install them

The great thing about them is you can change how strongly they hold/lock when at 180 degrees by tightening the screw. Its the PERFECT, PERFECT design. But only time will tell how long they last. Theres a little metal nub that will probably get worn down eventually, especially if you lock them kind of tight, like I need mine to be. But they WORK! SO HARD to find locking hinges like this.

While these hinges do rotate from 0 to 180 degrees, they only latch at 180; not at 90 and not at 135 though that is what the images imply. I was hoping they would have detents that keep them at 0 and 180 but the hinge is loose from 0 to 135 degrees. At 135 the cam hits the spring and you need to press it to rotate it to 180 where it latches in place. I mention this so others can decide if it is right for their application.

Well made. They did the trick for what I needed them for.
