    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.

    Purchased my Blum 24” drawer glides, and received them 1 week later. I was shocked by how fast my order was processed, shipped and arrived! I have three other projects planned for this summer and will definitely order all my parts for my upcoming projects
