In the loaded state, the clown presses a rope to the internal part of the cheek of "Grisha". It does not spoil and does not twist a rope.
The analog of Gri-Gri is applied to work with dynamic and static ropes with a diameter of 10-11 mm. It is successfully applied in industrial mountaineering, rock-climbing, the organization of rescue operations.
