    1 of 5 DO NOT BUY July 14th, 2026
    by Olivia from BROOKLYN, NY

    This is a completely illogical pull out kit. The bottom 2 shelves are wide and very hard to access. The demo pic is even a bit odd? It shows some small/short tupperware containers, I'm not sure what is meant to be stored in there. The top shelf is too short for oils/sugar, but too narrow for spices in 2 lines, plus you would have to label your spices on top? But then the lower shelves can't fit spices. I bought this because I wanted to use the full width of our pull out cabinet with a different shelf, but I really regret it. Ultimately, I ended up storing ziploc containers in here? but not even all the shelves are full.

    5 of 5 Great product! June 2nd, 2026
    by Nicole from Bogart, GA

    We got this product to turn a cabinet into a lifting shelf for the stand mixer. We had to take out the drawer above but regardless I love it and now have to have a cabinet door made to fit the new cabinet size. Love the product!

    Great price, fast shipping perfect fit for our lazy Susan corner cabinet

  • 5 of 5 | November 9th, 2026

    I had a hinge for a cabinet in the corner of my kitchen break. A local store didn’t have it, and referred me to cabinetparts.com. Although the hinge is apparently obscure, they had it. Delivery timing was as expected, and the hinge fit perfectly. Project

  • 5 of 5 | November 9th, 2026

    The product was received as stated and was in excellent shape. Installation was easy, and we are all pleased with the operation of the slide out garbage can holder.

  • 5 of 5 | November 8th, 2026

    The soft close Cabinet hinges were perfect.
