Arm | Coupler | Flange Socket to 1"/25mm Ball Socket

I used the Arm | Coupler | Flange Socket to 1"/25mm Ball Socket with the AMPS 2 hole mount to hold my Garmin Overlander GPS unit, which is not lightweight as far as gps units go. Held well, with no vibrations or movement, even while off-roading.

Really good quality mount arm at a reasonable price, hard to get these days.

Great stuff.

Works great for my GX470 with the GXBasecamp comms rail. Holds my phone and the remote faceplate for my radio. Works great keeping my phone lowe enough out of the sun and close enough to the AC vent that it doesn't overheat in the summer.

Class Act Operation - Great Customer Relations

I bought an extender rod for my GoPro and failed to note that the mounting brackets were for a 20mm ball and not a 1 inch ball. So needless to say it didn’t fit. I looked online to see if they made a 1” version but couldn’t find one on their site. I called the company and left a message describing my situation and asking for a recommendation as to what I could do. Tom called me back, told me he had 1” versions of the brackets and got them in the mail that day. His solution saved me money and was far beyond anything I expected. This is a great company with great (American made) products and employees. Buy from them with confidence.
