The RAM Tab-Tite HD spring loaded backing plate is known for providing quick and easy insertion and removal of a tablet but sometimes you want to leave your device where it's at. The RAM-HOL-ACNU is an alternative configuration that allows the user to fix their tablet in place. This configuration is ideal for high vibration environments or use cases where the tablet needs to remain fixed in the vehicle with a low profile mount for a low cost. During the assembly process, two nuts are inserted into the slots on the back of the Tab-Tite HD. The included Phillips screws are attached to the nuts and tightened, fixing the spring adjustment feature in place. The RAM Tab-Tite HD is compatible with over 40 sets of end cups to accommodate a wide range of tablets, with or without a case. The Tab-Tite HD is compatible with GDS end cups allowing you to charge and secure your device.
