Pull slack into the outer loop. Insert a split pin around the outer strap layer 10mm from the end. Attach the plastic shear torque adapter and a 13mm socket wrench. Rotate the key counterclockwise with the wrench to tension the strap until the adapter shears.


Remove the shear torque adapter and wrench. Swing the key over and engage in slots in clip.


Important Note

 Horizontal changes in direction, restraint spacing of 300mm maximum. Use Multistrap and/or Multicleat, as appropriate, to suit support structure. To ensure adequate restraint, Multistrap MUST be used at the mid-point between cleats on all horizontal and vertical straight runs:Quadrafoil
