  • 3 of 5 No screws included July 17th, 2026
    by Mindy from Warm Springs, VA

    I purchased the TIP ON adapter to accompany the Blum tip ons. To my surprise, these ship without screws! Was it an oversight or did someone think screws should be an add on to the order?

    1 of 5 Not Good June 24th, 2026
    by madewell from Hudson, FL

    when I placed the order on June 2nd I paid extra for 3 day delivery. I did not receive my order June 16th not really 3 days it was 2 weeks. I would like a refund on the shipping and I will be returning everything to. It did not arrive in time and it was very important like I explained to the customer service people

    4 of 5 Easy Install and Adjust March 18th, 2026
    by Brian from Crested Butte, CO

    Way easier to install and adjust than a horizontal hinge. Probably a wash on price.

    I have been using these hinges for years to replace the existing hinges in our community. They fit perfectly every time. No drilling of new holes or router work. Very fast and efficient delivery all the way from Florida to our small town up here in Maryla

    Like the products and prices. They arrived a little slower than I hoped, but in good condition. Wouldn't hesitate to buy from CP again.
