The front of the massive 1m x 1m longitudinal buried concrete bearer running along the line into which the forward pimples were cast. The posts supported barbed wire.
Behind this bearer are two similar parallel longitudinal bearers about 5 to 6m apart. These are now almost covered with soil.
The sharp angles in the Wall here may have allowed enfilade fire from dug-in anti-tank weapons along the front of the line.
