  • 4 of 5 Easy Install and Adjust March 18th, 2026
    by Brian from Crested Butte, CO

    Way easier to install and adjust than a horizontal hinge. Probably a wash on price.

    5 of 5 Love these door lifts August 6th, 2025
    by Mary from MIDLOTHIAN, VA

    These cabinet door lifts are extremely easy to install and have adjustment screws to fine tune their location. Soft close is a nice added feature. I love these for cabinets located above appliances.

    Good service. Had parts i needed in couple of days.

  • 5 of 5 | June 19th, 2026

    Tried finding the hinges elsewhere. Found them right away. Perfect match.

  • 4 of 5 | June 18th, 2026

    I was able to find the exact hinge needed to replace broken hidden Soss hinges in a Martha Washington cabinet. The price was reasonable. It did take a while to ship out (ordered May 15, shipping notice June 2) but then arrived quickly once shipped.

  • 5 of 5 | June 18th, 2026

    I have looked and looked for replacement parts for my cabinets and was about to give up hope, but thankfully they had the exact parts I needed. They arrived quickly, reasonably priced and I am thrilled.
