The MM80 Clip on Cable Guide Kit allows smaller cables or ropes to be easily used with the MM80 measuring machines. The kit consists of two guides, one for either end of the machine. They simply clip on the existing vertical rollers then the cable/rope is fed through the guides from one end to the other. the guides ensure that the cable/rope is always central to the measuring wheel when taught. These guides will accept cable/rope from 1mm to a maximum diameter of 15 mm. The guide bushes are made from stainless steel, they are not suitable for abrasive wire/drawn wire.
