    5 of 5 Excellent August 20th, 2020
    by Philip from Claremont, CA

    I needed an opening mechanism for a downward cabinet door. This mechanism was the only one that I found that would work in my situation. Installation was pretty straight forward. You do need to download the manual from manufacturer to figure out where to drill holes for mounting. The tension is adjustable. Soft close and soft open works extremely well.

    4 of 5 Easy install, wish it can have greater degree of adjustment August 20th, 2020
    by Philip from Claremont, CA

    I needed a special hinge for a cabinet door that opens downward. This hinge was easy to install, looks great with excellent workmanship. The only issue is that I wish it can be adjusted a bit more than a few millimeters. Overall, I'm satisfied with this purchase.
