Traffic Signal Posts

Jerol traffic signal posts can be supplied in 114mm, 168mm or 219mm diameter.
The size and diameter of the traffic signal posts required are determined from the matrix below.

There are 2 basic methods of connecting the traffic signal posts; head cables to the incoming plug and socket cable.

Dependent upon the type of cabling used this connection can either be achieved by a termination box located on the backboard in the door opening OR by an external termination box, mounted on the outside of the traffic signal posts, just above, and to the rear of the door opening.

The incoming supply cable is connected to the plug and socket by the electrical enclosure, which is mounted in an access chamber.
