Helical steel cabling fits inside the conduit running between your window opener and the operator handle. The role of the helical cable is to drive the gear box of the operator or opener whilst the conduit itself moves the opener forwards or backwards. Having extra lengths of helical cable on hand is always advisable in case of wear and tear within your conduit.
Here at Rocburn we offer T450 inner helical steel cable in metre long lengths. And we have helical spring stops available that fit onto the end of the cable to adjust the opening stroke of your window opener for greater ventilation.
