  • 2 of 5 9” Minimum Opening Concern June 16th, 2026
    by Stephen from Encinitas, CA

    I found the product itself very sturdy and of high quality. However, the minimum requirement of 9” is incorrect if you also purchased the hardware to attach the face of a cabinet door. The hardware that must be attached to the sides of front sides of the unit increase the total width of the unit and made the total width approximately 9-1/2”, which made it too wide for my 9-1/4” wide cabinet opening. For that reason, I had to return it. There is a 35% restocking fee, which I will dispute, because the company clearly says it only takes a 9” opening for it to work. I am still waiting on my refund, and I returned it over a week ago. Like I said previously, it’s a very solid and high quality unit, but the company needs to say in the product description that if you plan to purchase and add the hardware to attach to a cabinet door, you will need about a 10” cabinet opening for it to work.

  • 5 of 5 | June 19th, 2026

    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.
