An apparatus and methods for pushing conductors into conduit and other structures are disclosed. The apparatus (“pusher”) can include rollers to apply a pushing force to one or more conductors or bundles of conductors. One or more rollers can be coupled to a drive mechanism. The pusher is configured to pull conductors or bundles of conductors off of one or more spools, and push the conductors or bundles of conductors without de-bundling or sorting the conductors. The conductors can be fed through the pusher in any format including side-by-side, vertical on top of one another, twisted together, or other formats. The pusher can include a guiding device that is configured to route the conductors from the pusher to a conduit through which the conductors are being pushed or pulled.
