The CH-CC4P8M curly extension cable is the same as other extension cables except that it is in a spring style, curly form so that it can be used where components are subject to movement.
The cable has inherent flexibility and the spring form returns to an overall shorter length after being extended.
The CH-CC4P8M is 8m long when fully stretched with a working length of approximately 4.5m as stretching further will place too much stress on connections and may be dangerous to anyone close by should a mishap occur and the cable gets broken or a connection is undone while under tension.
