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.
