It secured to the truck mount with very little effort. The elbows secure pretty tightly even if the tablet puts a bit of a strain on it. As long as I used it where the first arm is horizontal and rests on the dash and the second arm is pivoted downward I have not had any issues. Works just like I had hoped.

Bought 2 holders. One for my tablet for my over the road truck and one phone holder for my lawnmower. Yes you read that right, lawnmower. First the truck. Ordered the bolt down base because I’ve already got too many things on my windshield glass. It would have been to much for the tablet to be up there too. Mounted on the side of the dash panel and it holds it great. All the rough roads I travel and the off road stockpiles I go to and it still holds strong. Don’t say it don’t move a little but I can always read it when needed. Second the lawnmower. Mounted it between my legs on a zero turn Kubota. Stayed in place while mowing with my ear buds in. Away from bushes and branches it is just the ticket. Had been using belt clip while mowing but after replacing 2 I phoned that vibrated out of the clip on rough land was enough. So glad I chose Tackform.

Overall I am pleased with this purchase. I have been researching methods to mount a tablet computer inside of my teardrop camper for a while now. I selected the TFEP-AM2AR12-TAB mount with dual-arms for the positioning flexibility as I wanted to attach the mount to the underside of the camper's cabin wood cabinets.

Initial observation; quality of the hardware appears to be good; manufacturing appears to be good; excellent communications by the seller; quick shipping. I will say that the mount can be a bit cumbersome to position with one tightening thumbscrew for two ball-joints, kind-of-a wet-noodle…but I was able to position for optimal viewing with a little patience. First deployment with this new accessory to my teardrop camper is mid-March 2020, time will tell the durability and reliability story…

I don’t plan on traveling with the tablet computer in the mount. No need for me to challenge the mount during transit and potentially damage the tablet computer, I will only clamp the tablet into the mount when the camper is parked. The mount seems to be sturdy enough; although it does flex with the weight of the Microsoft Surface Pro 4 tablet computer installed but not a deal-breaker.

The tablet computer weighs 1lb 11oz. and is 11.5-inch (W) x 8-inch (H). The mount holds the tablet computer securely using two short and two medium clamp-legs. In my application, I drilled through holes and used #10-32 machine screws with nylon insert lock-nuts to attach the mount to the camper's cabin wood cabinets.

I highly recommend this mount…

Trackform made my project easy and looks professional. I'd recommend Trackform to anyone looking for mounts at reasonable prices.

Works just the way I wanted.
