SAS A-Frame Deadweight Anchor

A-Frame Deadweight Anchor


The SAS A-Frame Deadweight Anchor is a portable anchor and is ideally suited to flat roofs with parapet walls between 300 mm and 1.8 m high. It can be used for both rope access and fall arrest purposes and provides two high anchor points. Assembly is quick and easy thanks to the spring-loaded sword pins; which eliminate the need for nuts and bolts. If used correctly, the pneumatic tyres will not damage roof membranes.

Friction, and therefore effectiveness, can be reduced in a number of ways:

  • Using less than the recommended number of weight plates (all 12 must be correctly used at all times)
  • The type of roof finish. For example, gravel ballast, concrete pavers, green roof, membrane etc.
  • Surface water
  • Icy conditions
  • Excessive roof slope
  • Moss / Lichen or other contaminants on the roof
