Abstract
A roller assembly for facilitating the drawing of a cable along a cable tray having a transversely-extending strut includes one roller having a rotation axis and an elongated attachment portion having a cross-sectional shape which is substantially U-shaped in form. The attachment portion is positionable about the transversely-extending strut of the cable tray by directing the opening of the U of the cross-sectional shape of the attachment portion over the strut. A fastener is used to bind the attachment portion to the strut. A second roller can mounted upon the attachment portion for rotation about an axis which is substantially normal to the rotation axis of the one roller for use at a corner or curve of the tray, and the componentry of the assembly facilitates the construction of a roller-bearing apparatus providing a multi-sided passageway through which a cable can be drawn.
