  • FINALLY, a phone mount for my car dashboard that actually works!
Style: Medium Arm
I have tried a bunch of different methods of mounting my phone in my car, and this mount was the first one that worked well for me. I like that this mounts to the actual surface of the dashboard. Personally, I pried up the dashboard cover, drilled some holes, and bolted this down onto my dashboard (I will be driving my car into the ground and don't care about resale value, but even if I did those holes are pretty small and would be pretty easy to make virtually unnoticeable by just filling them and adding a little dab of paint to match the color), and it is rock solid. I think it would probably hold pretty solidly if attached with adhesive (such as VHB tape) if one wanted to do that instead. The rubberized ball socket joints of the mount itself are also rock solid once tightened, so the combination of that and having this bolted down means my phone is very sturdily mounted to the dashboard, which is just what I want. The ball socket joints and nice long arm make this mount very adjustable as well. I was able to adjust the positioning so that while my phone is mounted, I can plug cables into it, the screen directly faces me while I'm driving, my view out of the windshield is unobstructed, and I can see and access all of the displays, controls, vents etc in my dash. This is the first mount I've been able to find where I haven't had to compromise on any of the above. Another perk of this mount is that it is part of a whole ecosystem of interoperable parts. RAM Mounts offers a variety of different parts and mounts that all work together, so you can swap out different attachment mechanisms for the base (like a suction cup for your windshield) or the top (like a cradle or a magnetic mount to hold your phone) if you prefer. I wish RAM offered a magsafe-compatible top for this, but the flat surface of this product makes it pretty easy to attach any stick-on magsafe mount. Overall, this is an excellent, very sturdy, highly adjustable mount that meets all of my needs and holds my phone reliably. It's also nice to be able to support an American company making quality products. ... show more

  • Perfect extension for mounting my GPS/Fish Finder on my boat.
Style: Long Arm
I have been looking for something like this to install my GPS/Fish Finder on my boat. My windshield is so low that there was no way to install the Fish Finder. But with this extender, it moves the Fish Finder far enough out to be able to mount it. Very sturdy.

  • Great Mounts for OmniTracs Units
Style: Medium Arm
These mounts are great for mounting OmniTracs units in semi's. They are universal and can be mounted in any brand semi. I run a fleet of big trucks and we purchased new trucks recently, I purchased a bunch of these off Amazon. They were shipped quick, all good quality and the price was great. We mount these with self tap metal screws. Easy to install and sturdy. ... show more

  • This will work better than you think it will.
Style: Long Arm
It's sometimes difficult to visualize how something like this can be used to mount your equipment, and I wasn't quite sure myself if this would work to mount my Garmin echoMap in our '96 Sea Ray. Being an older boat, the design is more "rounded", and since GPS and bluetooth technology was still fairly new, it wasn't designed with ease of mounting aftermarket electronics. Finding flat mounting surfaces without throwing off the general appearance, wasn't easy. This Ram mount was about the longest I could find, which I needed to be able to fit a marine GPS behind the sharply sloped windscreen. As it turned out, the Garmin base matched up to a set of the many mounting holes the Ram mount had, after a couple of twists to find them. Some stainless steel bolts, run the cables, and this became a very solid mount that has performed flawlessly for over a year now. Because of the length, it can vibrate a bit when running on the water, so I added a small felt pad to the mount arm where it might have rubbed against the dashboard material. Very happy with this, everything installed perfectly without any hitches. ... show more

  • Ram mount system just works!
Style: Long Arm
Came across the Ram mount system a while back when looking for a way to secure my iPad for use in my vehicles. They are little on the expensive side but they just work. In a marketplace of cheap crap products it's refreshing to find something of quality. Purchased this longer arm to give me more mounting options in my Jeep - I can have low for everyday driving, or extend up to use the tablet as a dash cam. Disconnects from the dash in less than 10 seconds so I can stow for security. Holds my heavy cased IPad securely with virtually no shake or sag. Only gripe is the design limits articulation certain directions when folded back, would be nice to have the notches for the ball mounts orientated 90 degrees from each other. There may be an arm like that, I'll have to research. Overall this seems to be a good quality item that should last. Highly recommended. ... show more

  • Easy SOLID Adjustments in Scary Places
Style: Long Arm
I used a few of these to drop closed circuit cameras down a few inches so the cams could better see under the eaves trough on the house. Since setting up cc security cams usually involves three different adjustments, these ball mounts make it EASY to set up cameras. Adjust cameras to approx. position and then do real fine tuning with the Ram mounts. Really nice when you're a geezer up on a ladder and are finally old enough to have a respect for heights. Should have used these mounts when I was up on top of a 12 story crane, would have been nice and fast and less scary with the Ram mounts for camera adjustments. I used this size ball mount Rams which was overkill for the lightweight cams but even in high winds, the cams don't wiggle at all. I will be looking at Ram stuff first from now on for mounting radios in cars, boats, and other vehicles as well as some more camera mountings. ... show more
