The RAILBLAZA Screen/Tablet Holder is a simple, cost-effective and flexible way to "grab your screen". Many iPad holders are just that, an iPad holder, the RAILBLAZA ScreenGrabba will hold an iPad, as well as many other tablets.  Some outdoor situations will require your iPad to be in a waterproof case - this is no problem for the ScreenGrabba, simply place the iPad in its bag, put it in the ScreenGrabba, and clamp it in, easy as that!  The Screen/Tablet Holder's spring loaded arms are sufficient for most applications, with neoprene rubber pads to give high gripping power.
