Stainless Steel Door Hinges, 3.5... vs Douper 200N/44lb Heavy Duty Gas ...

The hinge action is ridiculously smooth and tight with just a little resistance to the action indicating tight manufacturing tolerances. The edges are a bit sharp from the graining process. These are top notch and a great price.

These seemed defective. They feel unusually stiff to open and close.

Product works too well for what i hoped to use it for. Works like a charm. Thank you, for a useable and quality product.

Lid is 22” x 72”, and weighs about 35 lbs. Hope it holds up in the rain and does not rust!

Wood screws are only about 1/4 long due to the width of metal on the struts. Manufacturer owes me not just the' price of the lifts, but $350 for my time and materials, to install these. The instructions for this product are very bad.
