    20mm Flange Socket to 25mm (1 Inch) Ball Adapter

    BMS-20mm25mm

    This socket ball may be used to transform any of our fixed 20mm balls to a 1” machined aluminum ball. Once converted, the 1” ball can be used with third party arms designed for 1” ball mounts.

    Like all of our 20mm ball mount products, this adapter provides almost infinite adjustability thanks to the integrated thumbscrew and includes the Bulletpoint Limited Lifetime Warranty.

    Disappointed - Did not hold well

    Couldn't use for intended purpose. The clamp on the 20mm ball I had installed slipped too much - allowing the arm I attached to the 1in ball to fall forward.
    Design would benefit from 1) some type of surface in 20mm clamp to increase resistance and 2) larger screw **** for tightening.

    Hello Mike. Thank you for taking the time to write a review. It sounds like you were trying to use a 20mm flange on a 1' ball which is not going to work. We recommend using the flange for the 1' ball. Below is the link to them. If you have any questions please feel free to reach out to customer support. They are happy to help.

    Perfect fit.

    This is the only adapter I found online that accommodated a 20mm socket with a 25mm ball and the quality was so good as well.

    Great and unique adapters!

    They enabled me to add very nice automated bulletpoint phone mounts/chargers to the dash RAM mount of my B-Van. Perfect!

    Totally worth it

    I have never been so satisfied with a phone mount in my life. This assists in keeping my phone steady and in one place. I didn't have to return the mount because of this adapter, so it totally fixed everything. Thanks guys
