Review on RAM MOUNTS RAP B 200 12U Composite Double by Pat Nard

later As mentioned the halves are hexagonal on the inside edges as is the protruding edge of the insert around which the two clamps rotate. At first when I tried it on I thought the rim was stuck, but when I took it apart I noticed it. Why couldn't the insert be made round and the brackets too? This would allow infinite customization. This is to allow this type of installation so that someone is not fully aware of its use or as desired by buyers. You can clamp it on the tips of the hex, but it can get into flat surfaces or just hold the clamp a little wider open. Anyway, I adjusted it to be on the hex planes, rotated more than I wanted and then was able to rotate the clamps on the balls to get the 98% I wanted. For this reason I gave the item 4 stars. Using a Dremel tool, file, or sandpaper, you can round off the hex shape of the plastic just enough to allow for extra rotation and adjustment. However, it works when you need to position something offset and each clip needs to set the device at right angles.
