Mdf (medium density fiberboard) closet doors. They are heavier than standard hollow core doors installed in many houses.

Ball bearing hinges seem defective. Wont go into existing door mortise. Screws are too slim.

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.
