This consists of a stainless coated u-bolt base, double socket arm and diamond adapter base.

The diamond adapter base has a hole pattern that matches the industry standard AMPS hole pattern and will connect to a large variety of RAM Mount and third party cradles.

Included in this package is a U-bolt base that will accommodate rails from 12.7mm to 31.8mm (0.50" to 1.25") in diameter. A composite rail adapter can narrow the rail to a minimum width of 12.7mm / 0.5”. The mount is designed with a RAM 1" diameter patented rubber ball and socket system that has adjustment points at both ends of the double socket arm; this allowing for almost infinite adjustment and perfect viewing angles.

Wobbly but Usable
Color: Grey, Size: Standard - 4 Panel
A bit wobbly, but good enough for the price when you need a solid background for remote work calls.

Nice and easy to assemble
Color: Black, Size: Standard - 4 Panel
I absolutely love this 4-panel room divider! It was super easy to assemble — I had it set up in just a few minutes. The material isn’t too see-through, which gives just the right amount of privacy while still letting some light through. It does exactly what I needed it to do and looks so clean and sleek in my space. Perfect balance of style and function — highly recommend!

Sturdy, Easy to Use, and Great for Privacy
Color: Black, Size: 88" W, Color: Black, Size: 88" W
This room divider is exactly what I needed! The metal frame feels very sturdy and stable, and the wider bases keep it from tipping over easily. The fabric provides great privacy and blocks light much better than expected. I also love how lightweight and foldable it is, making it easy to move around or store when not in use. Assembly was simple and only took a short time with the included instructions. Overall, it looks great, feels high quality, and works perfectly for creating a private space at home. Highly recommend!

Not bad
Color: Grey, Size: 88" W
Claims to be non see through but you can, easy to assemble but instructions aren't good. Decent money value, quality is okay. Good fit, not very sturdy.
