I'm testing your 26 Series Diamond Mount along with your Perch Mount and the 3" Arm in a folding beverage holder application on my GL 1800 Honda Goldwing. I went with the 26 series because I wanted the extra holding capacity as our tests go up to a 32 ounce (2 pound) beverage and needs to withstand the shock and vibration of the terribly bumpy Wisconsin roads. After several hundred miles of road test with this set-up, I can tell you that your mount has not budged! Very pleased and would highly recommend the 26 Series for any large/heavy loads, especially in dynamic applications such as boats, construction equipment, motorcycles, ATV's etc.

I needed to put together parts to make a phone car mount for my dad. One of the parts I needed was a flat base with a 20mm ball, and this was the only option I could find online that would work. It turned out to be great quality, we really liked the all-metal build.
I knew I could trust Tackform after seeing them mentioned on Peak Design’s website, where I got the phone holder with a 20mm ball. I have it mounted onto Tackform’s base using a dual-socket arm for 20mm.

Much cleaner and more streamlined than the previous version. Much nicer materials too.

I put this in a 2010 Peterbilt. I made a trip out east with a load of heavy equipment, it is the best cell phone holder I have ever used! It was awesome!
