2 Packs [Upgraded] Qrity Cabinet Cupborad Furniture Door Lift Stay Support Hinge Damper - Support Up to 20KG - Opening Angle 75°/90°/110° - Come with Hex Key

Works great, but installation instructions only have millimeter dimensions; it would help to also show inches. Easy to convert, however, using Google.

We have a travel trailer with a full length cabinet over the bed with three doors that open upward. There was no mechanism installed that kept those doors open so you had to use one hand to open and hold the door up and open and use the other hand to get whatever you needed. A real hassle. These solved that problem beautifully!! Easy to install - took less than half an hour to do all three doors - holds the doors open and a breeze to close. Highly recommend these!!

Just awful. I needed them for a bunny hutch lid. The hinges need assembled with screws, plastic washers, etc. No instructions on how to assemble parts. Just send the completed hinges to be screwed in. It makes no sense. The hinges kept wobbling and wouldn’t stay put. Too bad I missed the return window. Going straight into the trash.

The media could not be loaded. I am using this on a DIY mobile workbench, with a 3/4" plywood top. After installing one, it was obvious I don't need the other one, so it's a spare. As others mentioned, instructions are pretty much non-existent. And I couldn't seem to get more than 2 angles, even thouigh it's supposed to have 3 options.. However it's fairly easy to figure out how the parts are assembled (actually just look at the pics on Amazon). For me, it was difficult to determine just where I should mount the bottom and top, based on the angle I want. I didn't want to just start drilling holes and making attempts until I finally get it right. The diagram I attached is one I found online for a very similar part, but different manufacturer. This really helped me a lot. My first attempt was not exactly the angle I wanted, but VERY close, and I stuck with that. It is working well as a lid stay.

My built in hamper door hinge gave out after 30 years, I looked for a simular replacement several times but I couldn't find one. Finally I was painting the bathroom and decided to go at it more seriously. This item gave me the solution. The door hinges on the bottom. This item gives it a slow open and hard stop feature. I first put a normal hinge on the lower part of the door to the cabinet. This thing stops the door from opening hard and maybe breaking things. The device doesn't come with great instructions but I think anybody could figure it out with a bit of thinking and the pictures they include. One point, the pictures for the new design are wrong, one of the brackets is what I would call strait and one has a 90 bend, which is like the assembly picture shows not the parts spread out pictures. The hinge had to be reversed to work opening down like it does. Most hinges can't be reversed like this. I'm including a picture of my installation which might help somebody.

There are a few important points about how this item can be used, but first let me say that I was able to make these items work, but if they had been high-quality, precision made parts, things might have been a bit easier. I wanted a soft-close on a desk for my kid. I originally bought the Sugatsune knuckle-style lid-stay that I've successfully used before on toy boxes, but found that the knuckle hit the bottom of this shallow ( 3 1/2 inch deep) desk compartment. Because both arms on this item are approximately the same length, I was pretty sure I could configure it to fold evenly, which I was eventually able to do.The configuration provided in the measured drawings in the rather skimpy instructions does requires a depth of compartment of approximately 5 inches. By moving the container-side attachment point about 1 1/2 inches down (away from the opening) and 3/4 inches toward the lid hinge, I was able to get it to fold more evenly, so clearance into the depth of the compartment was not an issue.According to the included lid-weight chart, my lid is well within the adjustment range of a single stay, but I found that once I installed one on the right-hand side, the lid slowly closed to about 40 degrees and then dropped without much resistance, even with the friction adjustment at full. So I mirrored the installation on the left-hand side and the lid was pretty hard to close, but no longer dropped hard. So then I removed the right-hand side, and lo and behold, the lid still closed slowly. The loss of resistance was just a bit of a defect in the one stay. It would have worked if I just wanted something to keep the lid open and not control its descent.This all jives with my impression of this hardware from when I first handled it. It's heavy duty and strong enough, but it doesn't feel precision made. It rattles a lot. I will probably not buy this lid-stay again, instead paying about double for the knuckle-type, just because those seems to be made to high tolerances and are nicer to work with. That said, this set of lid stays did work for me and I'm not worried they are going to break under the strain of kids playing with them.

Easy enough to install, but the instructions are worthless. Hinge collapses back in the cabinet a little more than desired. All good though. They do the trick.

First off, the instructions are terrible! If you try to install these using their instructions, you will be in a world of hurt. I test fit on a storage trunk, and the hinges would not even close completely using their measurements. I ended up eyeballing one side, and testing for fit. Then I replicated what I did on the other side. They worked fine in opening and holding the lid open at about 110 degrees. Closing is another matter altogether. They are very stiff to get started, then after the initial resistance, they give up and the lid slams closed. I have a light lid, but no matter how I tried to adjust the hinges, it was always hard to start the close, and it always slammed shut after the halfway point. They are the cheapest (cheaper) hinges on the market for a reason. I would not buy again.
