The SnakeAnchor serves as a lanyard and anchoring device, and can be continuously adjusted (2.7 inch intervals). It can be installed open and used as a friction device with pulley or biner in the desired length. It also can be installed in choking mode and continuously adjusted as well. 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.
