New doors. Used on exterior doors. Works as advertised. This is an example of one and your mileage may vary.
Ball bearing hinges seem defective. On every hinge i have ever seen, the bottom of the hinge has a hole so you can pop out the pin.
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.
