Q: 1. Is there a way to adjust the friction tension? If I were to release the tension to reposition what prevents moving?

A: The FLM 47GX Centerball Tripod Head with SRB-40 QR Clamp has a friction tension knob. You can adjust the friction tension by tightening or loosening the friction tension knob.
