This compact phone or small tablet clamp (up to an iPad 10.5") can be used with the Tripltek tablet brackets in case you wish to use a phone instead for the Tripltek tablet. 
It mounts the same was as the Tripltek with the thumbscrew.
We also use this clamp on the LifThor Loki for DJI FPV remote control.
