Douper 200N/44lb Heavy Duty Gas Springs Lid Support Hinge Pneumatic Lid Lifters with Soft Close Support Heavy Drop Lids and Work Perfectly for a Soft Close Pack of 2

The gas spring lid support hinges worked great for my chest project. Now, I feel that the chest is finally safe, particularly for children. For potential buyers, there are a couple things that I would note to improve your experience: ① At first glance, it may appear that you’ve received 2 lefts or 2 rights, yet what you have to do is remove the screw from the disc, flip it, then reattach. Initially, I was upset at the prospect of having not received a true pair and was going to reach out to the seller until I realized that I could flip the disc. ② The screws that it comes with are tiny, wimpy, and, in my opinion, inadequate for use, especially considering the force of the gas springs. I went to the hardware store and got respectable screws which were much much stronger for the job. I suggest that you do the same. The manufacturer and seller really ought to size things correctly for good staying power.

Super smooth opening and closing. Held the heavy lid just like we were hoping.

Excellent product, exceeded expectations on heavy toy box lid. Only needed one to successfully soft close.

The product description on Amazon is confusing - it cannot open to 90 degrees by design. The enclosed instruction says 75 which is truth. The product is a good quality, but designed for heavier objects and may be too strong for a regular wooden door or boxtop. Slams to open, may be dangerous.

I have been thoroughly impressed with the performance. These automatic slow lowering safety pneumatic lid lifters have completely transformed the functionality of my lids. They have a heavy-duty construction. They feel solid and sturdy, giving me confidence in their durability and ability to handle heavy loads. Installation was a breeze, thanks to the clear instructions provided.
