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

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.

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.

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

Snaps right into my existing cellphone mount. Seems 17mm is the standard size.

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

Ball adaptor for a good price, it works only thing is it took a long time to ship

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

Pleasantly surprised by the quality of the adapter. It is constructed of steel and has a textured finish on each on the 17mm and 20mm ball ends of the dog bone adapter. It worked perfectly!

The 20mm ball end was under-sized, so would not tighten in the fixture without using electrical tape.

I needed this adapter to attach a phone mount (that uses a 17mm ball) to an extension arm (that uses a 20mm ball), and it worked perfectly. All aluminum means its heavy and strong, and the best part of this adapter is that the metal balls do not warp or flatten out when you tighten the clamps (unlike a plastic version). Worth the extra cost over plastic for sure.
