Tackform Ball Coupler

After changing motorcycles I found that my handlebar-mount Tackform iPhone holder could not be used. I had a 1” ball-stud which could be used but no way to connect to 20mm ball on iPhone holder. I was very pleased that Tackform offers all individual components separately and purchased 3.75” Stud Arm adapter which works perfectly. Very good quality and function.

Works Great

Works as described. Would buy again if needed.

Great Product

This phone mount is of excellent quality, very easy to install and easier to use.
I have refereed friends to purchase their own.

Best of all the mounts I have tried

... And I've tried them all! Finally got to take a ride on some rough roads and it didn't budge. I left the retainer off on the way home with no problem. I highly recommend this phone holder. I already had the ball mount on the bike from the last few popular brands. This is so much better.

Perch mount

I bought the chrome perch mount for my 2015 road glide and I love it. Best mount ever. Looks good and holds my note 8 with no problem. Awesome mount

Built like a tank

This is pretty solid as it comes with an all metal arm and cradle w/industrial springs to secure your phone. Its a one handed solution for placing your phone. That’s an IphoneX w/otterbox defender case and that thing is not going anywhere. Stay away from the cheap Amazon phone mounts and invest your money on this setup you will not regret it. Money well spent love this phone mount. 👌
