The KAA is a self contained mechanical advantage system for tensioning lines or lifting people during rescues. In addition, as the KAA is certified to EN 354, it can be used for workplace stabilization, as a restraint system (open/closed), and for controlled lowering. Its strap-based construction makes it the most compact and lightweight system on the market. Depending on the orientation, it offers a 4:1 or 5:1 lifting ratio with an efficiency of 91%. The KAA is packaged compactly and ready for immediate use, so that no valuable time is lost when it is required. A swivel is provided at each end to prevent the system from twisting. The hand lever on the draw cord makes it easier to pull and can also be used as a lowering lever. The KAA is available in three lengths: 0.8 m, 1.5 m, and 4 m. The smaller systems are ideal for arial rescue operations, while the 4 M system is better suited to tasks like high angle rescue or pretentioning spars when installing cabling; circumstances where more throw is needed to work efficiently
