RAM Mounts X-Grip Universal Holder for 7"–8" Tablets with C-Size Ball (RAM-HOL-UN8BCU) is a spring-loaded four-leg cradle for most 7"–8" tablets, holding devices 64–146 mm wide (up to 22 mm deep) with or without a case. Easy-access grip knobs on the back release the tablet quickly, and the rubber caps hold it firmly without covering the screen.
