    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

    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.
