Seat Rail/Floor Bolt Mount | 21" Rigid Aluminum Neck | Phone Holder

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.

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

The BEST phone holder in the world

I’ve purchase over 6 different car phone mounts for my iPhones only to have the cheap plastic materials and poor design fail. Sometimes in only minutes. I did some research and came across Tackform and their claims of a solid all metal product. I also wanted to hard mount the holder to my truck and they offered that as well with a design to bolt it to my seat mounting bolt that did not require me to drill and holes in my beautiful new vehicle. Everything arrived as promised. The product is exactly as described and installation took only 2 minutes. It’s been several weeks now and the mount is perfect. It’s heavy duty and stands up to my rough demands of it. The part of the mount that holds the phone is super strong with a spring design that’s simple and elegant. My mount uses a gooseneck design that’s long. In the past these types of mount would swing around and loosen due to the truck turning and the weight of the phone at the end of it. My mount hasn’t moved a bit. It’s rock solid. I can’t believe I waited this long. It costs only a few dollars more but it’s worth every cent. I was not able to find another mount in the industry that offered the features tackform offers. I wish I could offer my personal info for anyone that wanted to follow up. This is the best.
