Tackform 20mm Aluminum Ball to 17mm Ball Adapter Compatible with Garmin and Other GPS Devices with 17mm Balls

Made it so I could mount my car charger into a mounting system with 20mm balls. And a little cheaper than other manufacturers out there. Had it for about a year and it still works!

Nicely milled and great finish.

Great quality, the ridges help adhesion and it fit perfect with my Bulletpoint arm to otterbox magsafe charger!

Need to be a little thicker. But if you add some rubber will work better, size is perfect

Purchased to match up a different holder for a phone, using the bulletpoint mounting system. A little expensive for a small piece of steel but it’s life I guess

Does what it is intended to do.

I used this to attach my Furrion camper camera monitor to my Bulletpoint mounting system in my 21 F250. It worked fine, although the fit into the Furrion socket was pretty tight. Took a good bit of force to get it in. I guess the good thing is it actually holds its position pretty well, as the monitor is fairly heavy.

I recently bought some Bulletpoint mounting systems for two of my vehicles. I already had a charging phone holder I still wanted to use but they didnt fit the Bulletpoint system as it came. I needed these adapters and they worked perfect. They have held them great and Im very happy with them.

Works perfectly for the application that I needed very stable fits my mounting options would definitely recommend this product

Great for mounting 17mm ball devices to my 67 design Jeep Wrangler 20mm mounts.
