The popular Nano-Lok™ webbing block with double scaffolding hooks. The Nano-Lok™ is one of the lightest blocks on the market, and thanks to the fact that it sits flat against the back, it is also very easy to use. The block has a built-in fall arrestor and has a strap length of 2m.
The block comes with a special carabiner that can be integrated directly into the harness. This allows the block to lie flat against your back and you do not need to attach the block to the rear anchorage point. This carbine can be replaced by a regular carbine (self-locking requirement). It is okay to use an extender that is max 40 cm and is approved as an extender.
