ABSTRACT:
A roller is provided in combination with an electrical junction box to facilitate pulling of wires through the box. The roller has a spring mounted plunger on one end adapted to be received within a pre-existing hole in a side wall of the box, and a press-fit stud on the opposite end to be received within a pre-existing hole on the opposite side wall of the box. The plunger and stud rotatably support the roller within the box so that wires can be pulled over the roller by a person at a location remote from the junction box. The roller can be quickly and easily installed in the junction box using only one hand.
