Connecting to two 6 ft. Nano-Lok SRLs, the Twin-leg Anchorage Connector enables you to have 100 percent tie off. The best thing about this connector is that it attaches to your harness's webbing below the dorsal D-ring, allowing you to work without your self-retracting lifeline bumping into the back of your hardhat. The other unique component of the Twin-leg is its plastic blue insert. This small piece ensures a more fluid motion and added comfort. Try this connector with the following Nano-Loks: 3101254, 3101252, 3101251, 3101211 and 3101210.
