G-Lock is the new Gitzo leg locking system. The locking mechanism has been completely redesigned in order to achieve a 20% increase in rigidity, faster operation and stronger, safer locking. G-Lock's special design also provides a "gravity lock" effect: the higher the load applied vertically to the leg, the stronger the lock.
Safe Lock is a special techno polymer that maximises locking torque and equipment stabilisation. It is used on the upper discs of tripods and heads, and in applications where the equipment is rotated and screwed onto the support to eliminate micro movements and vibration.
