Allows the friction to be varied during descent according to the weight of the rope and/or the load.
可依繩粗細或下降體重量做多種選擇,改變摩擦力
The number of bars in use may be easily increased or decreased during a descent to obtain the desired amount of friction.
五個輪軸在下降中可增加或減少以維持適當的磨擦力
Good distribution of friction and heat helps protect the rope.
很容易的分散繩子的磨擦和熱度,減少繩子耗損,以保護繩索
For use with 1 or 2 ropes, diameters from 9 to 13 mm.
可供9~13mm繩使用,可打雙股,一至兩條繩索使用
