The SAS deadweight trolley anchor is a portable anchor device intended for use in industrial rope access and fall arrest. If there are no appropriate anchor points on a roof, the deadweight trolley anchor can be used. It is designed for use against a parapet wall but you can also use it against structural handrails / balustrades. It’s important to realise that it works by the amount of friction it exerts on the surface that it’s used on. With this in mind, the roof slope should be no more than 5 degrees downward slope from horizontal in order to avoid movement. Where possible, deadweight anchors should be backed-up.

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

- 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
