ABSTRACT:
A guide such as a roller and bracket means to feed electrical wires through conduit when wiring a building or other installation for electrical service, comprising a first bracket having hook means to mount to a junction box or to a second bracket, the first bracket also including an axle supported by said hook means, a roller mounted for rotation on the axle, whereby the roller is positioned for alignment with the open end of an electrical conduit connected to the junction box when the first bracket is hung thereon or on said bracket. Electrical conductors can then be fed smoothly and freely over the roller, into and through the conduit without scraping or catching on a portion of the junction box or other structure. The second bracket is used when necessary to face the roller sideways, or at a right angle to its position when the first bracket alone is hooked to a portion of the box. The second bracket includes a flat surface portion having apertures to receive the hooks of the first bracket, and connecting means to connect the second bracket and the junction box in a way to position the roller on the axle of the first bracket in said sideways or a right angle position. Both brackets can be connected quickly to already provided apertures or screws in the box itself.
