Jerol traffic signal posts can be supplied in 114mm, 168mm or 219mm diameter.
The size and diameter of the posts required are determined from the matrix below.
Electrical Connections
There are 2 basic methods of connecting the signal head cables to the incoming plug & socket cable.
Dependant 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 post just above, and to the rear of the door opening.
The incoming supply cable is connected to the plug & socket by the electrical enclosure, which is mounted in an access chamber.
