Nano-Lok™ Edge is a fall protection block that can handle sharp edges down to 0.50 mm in radius. The block has a self-retracting rope so you don't have to wear a dangling strap and you don't trip, which further minimises the risk of falling. Thanks to the backpack-like design, the block always fits snugly against your back and distributes the weight evenly. The block has a durable and impact-resistant casing.
