The RAM-B-189BU double suction cup base is a double 83mm twist lock suction cup base with NO BALL HARDWARE. Included is a hole pattern that will allow attachment to all RAM bases that contain the universal AMPs hole pattern.

The typical base used is the RAM-B-202U round base with 1" ball or a RAM-202U with 1.5" ball. RAM-202U is a better alternative for high vibration environments. Compatible arms and bases to go with this include the "B" series RAM-B-101U and RAM-B-103U but can also accommodate a "C" or "D" size ball base (RAM-101U or RAM-D-101U).


This forms the basis of a rock solid aviation EFB mount.

Solid Shelves
Style: 36inch 4 tier, Style: 36inch 4 tier
These are easy to install with the right tools. (STUDS ARE KEY) The only thing to note is, that when assembling the pipes, it takes patience for them to tighten. BUT IT DOES! DONT GIVE UP!!💁‍♀️ They are sturdy, roomy shelves, and very very stylish. The color is very spot on. The shelves in particular, function just as described.

Very good product! Gorgeous wood
These 4’ wide shelves are very nice. The wood is blond and gorgeous. I bought 2 sets. The hardware is very heavy duty iron piping!

Great when installed. Some problems
Style: 48inch 2 tier
The shelves are assembled and installed on my wall. I'm happy with them. They look great and are very sturdy. What prevents a 5-star rating? The instructions were poor. Not a huge deal as I was able to figure things out. The wall anchors that came with were cheap and (in my opinion) unusable. I went to Lowe's and bought some drywall anchors that were rated for 79 pounds and they worked well. During the install, I wasn't sure if I should attach the wall plates and assemble the shelves on the wall, or assemble everything and then attach it to the wall. Assembling before hanging was the way to go but it took two people. One other minor thing: The shelves are stained on one side an not the other. Since I have them high up on a wall, I'm looking at the unstained side. Yes, I can stain the unstained part, but it would be nice if they had just stained the top and bottom at the factory.

Beautiful Shelving Unit
Style: 48 inch 3 tier
The shelving unit is beautiful. It has not been hung yet, but I plan on using it to replace my entertainment center and hang my TV above it. I am so excited as the shelves matched perfectly to my furniture so I believe it will be a lovely addition to my living room and take up less space than the entertainment center does.
