  • 4 of 5 Great brackets October 5th, 2025
    by Janet from Salt Lake, UT

    The brackets themselves are very sturdy and will hold a lot of weight. Slight drawbacks are the plastic inserts for the holes which are rather fragile, and several of them broke even with gentle persuasion to get them in the holes. The holes themselves sometimes have a little extra metal or paint around them that you have to scrape to get the plastic inserts in.

    5 of 5 Strongly recommended company and parts February 25th, 2023
    by Lucille from LOS ANGELES, CA

    After a long, broad local search for longer, stronger and white shelf supports, Cabinet Parts was found online. The exact length needed with comparable prices to the shorter models was shortly received with easy installation, and had the excellent strength/support required.

    4 of 5 Good Brackets September 9th, 2022
    by Albert from Rainier, OR

    These brackets came quickly and were installed in a shed double door opening. The shed was leaning on the door opening side and I was hoping these brackets would square it up and strengthen the side. Unfortunately the brackets were too small. They did help but couldn't hold it from leaning out of square again. Not really the brackets fault. They're just too small. I need to find brackets a minimum of 24x30 I would think. Hard to find.

    5 of 5 excellent brackets September 8th, 2022
    by Sheena from Winter Park, FL

    We bought these for our pantry for the smaller side and actually has to use them "backwards". We wanted all brackets inside pantry to match and our other wall had very deep shelves. They worked wonderfully and they are extremely sturdy. So grateful to find this company online and get what we need at a great price.

  • 4 of 5 | July 20th, 2026

    Product looks fine. However the box it came in looked old and dingy. I wondered if I was getting someone's return. In any event, I think it's okay. Won't be installed foe a few weeks so will find out then.
