Berta 10 Inch 100N/22 LB Hydraulic Soft Open Gas Springs/Struts for Cabinets, Furniture Cabinet Doors Lift/Lid Stay/Support Hinges for RV Platforms with Brackets and Screws (2, Silver)

Great replacement strut for a custom storage box lid. The cheap ones that came with the box broke within a year, but these are well built and fit perfectly!

I ordered these for a trunk that I needed to put a lid lift on. The lid is flat on the underneath side and therefore, this particular product will not work. It needs to sit inside the lid and attach to the side. So, unfortunately, while it doesn't work for me, I was happy with the quality and the price. It would have been perfect if I had a way to attach it.

These are fairly easy to install if you can convert MM to Inches in the USA.Strong little struts.

Ok, when you read the instructions, it will seem like a lot of work for multiple door installation because the mechanisms require accurate hole location within about 1mm. The instructions that are in the video are good, it's just a lot of work to measure and mark and drill so many times. You can save your self hours by using templates that are reversible for left and right sides as shown in the pictures. Align the templates with the bottom front edge of the cabinet and the top and side edges of the doors. Best to clamp the template to the door and cabinet when drilling the holes. Do one cabinet first to make sure your templates are accurate. Once your holes are drilled mount the two brackets on the cabinet and doors and then reattach the door hinges as in the video. Mount the hydraulic cylinder by pressing onto the two "balls" of the bracket. Check to door to see if it operates easily. If it does continue to remove all of the cabinet doors you are doing. Use the templates to drill all of the holes on both the cabinets and doors and repeat the installation. It took about an hour to remove all of the doors from the hinges, measure the hole locations as shown on the schematics for 80, 90, or 100 degree lifts and drill holes in the wood templates and mount the hardware and reinstall the door. Since my templates were accurate I drilled the remaining cabinets and doors and mounted the next 3 doors in about 30 minutes total. The trick is to work very slowly and make sure your templates are accurate. In the end it took me 1.5 hours to do my 4 doors and they work very smoothly. Since it takes a while and some people have complained about defective lifts, I bought 4 extra sets of lifts for $26 . This way, as time passes, and lifts fail I can just pull off the cylinder off the ball brackets and press on another with little or no work. Way easier than starting from scratch. Good luck with your installation.

I didn't realize this doesn't work outdoors in the cold

First I will say so far so good. I just installed two on two rv cabinet doors. There were no directions so I had to think it out. The amazon product pics showed one with location measurements. I used the bottom ball joint measurement as a guide. It said 9 7/10” from top of cabinet to center of ball joint. Well my ruler does not have 10ths so I used 9 3/4”. My side wall cabinet box was not thick enough so if you zoom in you can see I cut, painted, and installed a block to hold the bottom ball joint secure. After installing the bottom ball joint I placed the upper ball joint/hydraulic arm under the raised door and penciled in where I wanted it making sure the arm would not hit the side of the cabinet when closed. I secured the upper ball joint and arm and it closed and opened nicely. I bought the 90 degree option but i placed my upper ball joint to where the door raises just under 90 degrees so not to put too much stress on the door hinges.

I worked for weeks on a project and ruined it with trying to install these hinges. I bought them to hold up the lid of something like a toy box. My lid was aligned perfectly and flush, but once I installed one of these hinges, it twists and misaligns the lid. “Why?”, you might ask. Because their measurements are not in inches, their device is not made to be installed with American tools. I have no problem converting MM to insides but find 7/10 on a measuring tape for me, or 11/32. Converting that further to 8th’s, it’s 5.6/8 for example. The entire thing was like that so needless to say I did not install the upper bracket in the proper place. Regardless of where I move it to, it still twists the top. The top is only 18” wide so it’s not like the hinge can’t handle it. So now i have bunch of holes on the inside of the lid where I attempted to correct it. If you’re going to sell something in America, how about making sure we can properly measure the required holes.

They didn’t work for what I wanted them for, but that is no one’s fault but my own. They seem to be quality pumps, and I’ll keep them for a future project!
