Sterling’s 8mm Screwlink, also known as a maillon or quicklink, is constructed from steel and can be used to attach a bight of rope to a piece of metal that may be too thin to safely attach to the rope directly, such as the becket on a double-sheaved pulley, a bolt hanger; or used when the connection point is too small to allow the rope to pass through properly.
Tech Tip: For your aerial apparatus rig, use a screw link between the swivel and the anchor material (Rope, span set, nylon slings etc) and an Auto Locking carabiner from the swivel to the Figure 8 or Hollow Blocks. When using a lower out system LOS, tie the rope directly into the swivels top end and carabiner/ screw link the aerial apparatus off the bottom of the swivel. This is a more compact rigging design with 1 less component to monitor due to the direct rope tie in. A Figure 8 “follow through” is a strong/ easy to untie knot to use.
