This Temporary Rope Static Line from Ferno uses 16mm kern mantle rope with a wind-up rope tensioner. These static lines can be extremely useful in height safety situations where lateral movement is required. Spans must be over 4m between anchors and end anchors must be structural and spans over 10 metres require intermediate anchors.
You must be careful to calculate the fall distances given the stretch and deflection these systems can have.
Best used as a total restraint line where possible.
