    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.

    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.
