Worked perfectly

I ordered many parts from this company and everything arrived quickly. I had a extra piece and it was very i easy to return. Would recommend them.

Tackform Resolved my search

Tackform arms are awesome in style and awesome in function! I love it! I was looking for an arm that had adjustments in the middle. Tackform had that. I was looking for a 20mm ball to 25mm ball. Tackform had that. I ended up getting both. And it’s something im proud of, decision wise 🤙🏻

Those rotating end pieces allowed me to get my device in to a position the Ram mount would not.

Garmin 890 mount in Ford E450 Motorhome

Appears to be extremely sturdy & just the perfect height arm when used with the expandable cupholder mount. Passenger can swivel screen to help with navigation and none of the dash instruments are blocked! Also our rear & lane change camera views remain functional while using our GPS. We just need to get on the road now.

Works perfectly!

I added this to my iPad mount on my bike. Perfect adaptation for my setup.
