Weightanka can easily be assembled by just one worker. Easily transport the system to another site or leave on the roof for future work.
Supports Multiple Workers
Supports Multiple Workers
Weightanka protects your people. It can be used as an OSHA compliant anchor for one worker in arrest or two workers in restraint*. This means that it can safely arrest a falling worker, but can also be used to restrain two workers from reaching the edge when properly tethered.
