Leofoto MA-30 Rapid Lock Inverted 30mm Ball Head Arca Swiss & Picatinny Compatible

The Rapid-Lock system from Leofoto offers unique safety stop features. A steel pin with a diameter of 5mm engages holes in the rail with a diameter of 5.5mm. The interface avoids unintended repositioning of the rail within the clamp when the quick-lock is engaged, in addition to enhancing the typical friction-based clamping method. The diameter of the ball is 30mm. The lock knob on the MA-30L locks and unlocks the clamps.
