The one-and-only combination system of tube shaped ring, parallel sewn 8 mm polyamide rope as well as segment stitching makes for a strong, versatile and easy to use tool in everyday work situations. If you want to secure or block the choked sling, you just need to install a small binder into an open rope segment right in front of the ring. Climbing ropes can be fastened as lower anchor. This way you can for example install a lowering device for aerial rescue at any given place.
