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 top end of the swivel and use a carabiner or screw link to attach the aerial apparatus to the bottom of the swivel. This design creates a more compact rigging system with one less component to monitor due to the direct rope tie-in. A Figure 8 "follow through" is a strong and easy-to-untie knot to use.
