The Nano-Lok can be used in place of lanyards and can be directly attached to any harness, reducing fall clearances. Connector installs to the harness webbing leaving the dorsal D-ring free for other equipment or rescue. The Nano-Lok retains tension on the lifeline at all times, keeping it out of the workers way and reducing dragging, snagging and trip falls. The automatic activating arrestor locks quickly to stop falls within inches reducing free fall distance and providing greater protection at lower heights. Dynema webbing provides excellent, cut, abrasion, chemical and UV resistance. Extended length Nano-Lok for applications where 6 foot unit is not long enough. Lightweight aluminum locking nose rebar hook ideal for use with many types of concrete forms.
