    These locks were identical to previous purchase and there were no hang-ups. A very good product that was easy to install.

    3 of 5 Cabinet locks September 28th, 2018
    by Jacob from Huntersville, NC

    I ordered some locks from a link I found when searching the parts I needed, once I put those parts in the cart and started looking for other parts I needed I found the website to be difficult to navigate, slow/no response from customer service and ultimately went elsewhere for the other parts I needed. It is not likely that I will return to this site to order again as I need or prefer a one stop shop when jobs come up and I need everything to complete a project in a timely manner.

    Shipping was fast and I love the pulls! They matched with my existing knobs and gave me the look I was going for.

    I realized they had sent a different part for one of my under mount latches. I called them and they sent the replacement part in just a couple of days.

    Easy to install. They were heavier (150#) than the originals(100#) installed in 2006. Very easy to pull. Excellent. W. O. B.
