Recently some buyers ask us about the new security mechanism of the Benro ball heads (specifically B, V and G series)… “Hey, I can’t release the QR plate from the ball head, the knob stopped loosening at halfway with only click sounds! Is it malfunctioning? Or is there any trick to make it open?”
Certainly it’s not malfunctioning. It’s actually the new Security Lock Design of the Benro ball heads, which was designed to prevent accidental dropping of the mounted equipment.
The security system works by adding a “safety position” in the knob of the quick release (QR) clamp. When the safety position is reached, the QR clamp will stop loosening even you keep rotating the knob. You need to slightly PULL the knob outward and then continue the rotation, so as to totally loosen the QR plate.
The following illustrations and manual clearly describe the mechanism:
The safety mechanism is built in Benro B, V and G ball head series. They are all in Arca-Swiss Quick Release Standard, that accepts all QR plates in that style, such as RRS, Benro, MeFoto and etc.
