A lifeline that doesn't penetrate your roof

Wireanka is a deadweight anchor system with a flexible horizontal lifeline. Designed as a temporary solution for flat roofs, the system will not penetrate the roof surface.

Fully freestanding

Wireanka does not penetrate the roof. The system uses freestanding Weightanka units as bases and has rubber moulded weights that are designed to protect the roof and not damage it.

Can accommodate more than one user

Wireanka is suitable for up to two users working in fall arrest and multiple users in restraint, dependant on configuration.

The system must not be used as a support for rope access (abseiling) systems. An alternative product, Accessanka, is available for this purpose.

Use in both wet and dry conditions

Correctly configured, Wireanka can be used on any of the following roof surfaces in wet or dry conditions:

  • Single ply membrane
  • Asphalt
  • Steel ladding
  • Concrete
  • Stone chippings (brushed)
  • Mineral felt.
