Tackform Enduro Series 21" Seat Rail / Floor Mount for Cell Phones.

This is a heavy-duty, commercial-grade mounting solution backed by a lifetime warranty. This is commonly used in commercial trucking, contractor vehicles, and municipality.

This gooseneck is made from a rigid 10mm thick aluminum rod. The rigid aluminum goosenecks are better suited when you want to have a fixed mounting location without frequent repositioning. The 3.75" arm at the top of the gooseneck has dual omnidirectional ball and socket joints allowing you to get dialed into the perfect position.

Vehicle Compatibility - Our TFEN-SR21-SPR has two different mounting brackets, the seat rail bolt bracket and the floor mounting plate.

The seat rail bolt bracket works on most vehicles that have an accessible floor bolt. This is not compatible with all vehicles so we recommend checking your floorboard to make sure you have clear access to the bolt - Please reference the product graphic to get a better idea of mounting options. The mounting bracket can be rotated so you can mount on vertical or horizontally positioned floor bolts.

This kit also comes with a second mounting bracket used for other install mounting applications when you don't have an accessible seat rail or floor bolt.

Phone Compatibility - This cradle will hold all phones under 3.4" wide to 5" thick.

very good article, I use it for my iPhone 13 pro max and for my iPod touch in my Toyota Corolla 2017 vehicle, I recommend it. all my supports for ipad and sound equipment are tackform, because tackform is quality and security.

Jerry Y. (St Louis, US)

I was tired of trying the usual phone holders. I didn’t want to glue anything to the dash of my new truck and suction cups never hold very long. When I saw this one, I knew I would have it from now on. Easy to mount and basically indestructible. It doesn’t block my vents and is right at my fingertips. Highly recommend this holder
