The Difference between Anchors and Anchorage

A regular issue we see in training is a misunderstanding around what is an anchor so we are going to take a minute now to explain.

The structure to which we attach an anchor is called the Anchorage.

Examples of anchorages are;

Walls, floors and rooftops


Large trees

Steel/metal structures


The anchor itself is what we attach to the anchorage.

Examples of anchors are;

Steel Slings

Hanger Bolts

Beam Clamps

Fabric slings

Forged Eye Bolts

Purlin Anchors

To the anchor we afix our ropes or we attach devices to enable a releasable rope access system. Many people seem to misundertand this so to be clear the devices are not the anchor and as such do not need to conform to the strength requirements that anchors do.
