A cable grip includes structure to stabilize and center the grip on a cable.

A system for pulling wire behind a wall is provided. One embodiment comprises a cylindrical weight defined by an outside diameter and a first length, and a tubular body with a hollow cavity defined by an inside diameter that is greater than the outside diameter of the cylindrical weight and a second length that is greater than the first length. A distal end of the tubular body includes a tip configured to penetrate a material that is behind the wall, wherein when oriented in a vertical position behind the wall, and wherein in response to drawing the cylindrical weight upward through the tubular body and then releasing the cylindrical weight, the cylindrical weight travels downward towards the distal end of the tubular body and impacts the tip such that momentum of the downward travelling cylindrical weight is transferred to the tip, thereby driving the tubular body downward through the material.

A press fitting for an electrical conduit includes a fitting body and a press connector in a press-connection section of the fitting body to allow press-fit connection to a conduit. A conduit retainer in a conduit retainer section of the fitting body releasably grips and removably retains the electrical conduit in the fitting body before the press-connection section is deformed radially inward during the press connection process.

A wire puller may be provided. The wire puller may comprise a middle portion, a restraint frame, and a front portion. The middle portion may comprise a gear box, a front bracket, a back bracket, and a capstan. The gear box may comprise a drive shaft and the capstan may comprise a hook pin. The restraint frame may be attached to the back bracket. The front portion may be attached to the front bracket. The front portion may comprise a pivot frame, a tube, an arm, a first side plate, a second side plate, a roller, and a flip out support. The pivot frame may comprise a locking mechanism.

A stub-up is provided for being anchored to concrete slab flooring in which conduit is embedded and through which electrical wiring may be extended. The stub-up comprises a one-piece hollow body having an upper end providing an electrical box and a lower end providing a base permitting the hollow body to be anchored to an underlying concrete slab in an upstanding position. The hollow body provides a wireway for electrical wiring from the slab to the electrical box. Wall structures and methods are also disclosed.

A cable puller in accordance with some example embodiments is configured to pull rope or cable through a conduit. The cable puller includes a puller frame, a capstan rotatably mounted thereon, a boom mounted to the puller frame, and a handle extending from the boom. The handle can be pivoted to a variety of positions relative to the boom. A lock locks the handle into a desired position relative to the boom. In some embodiments, the boom is mounted to a wheel assembly, and in some embodiments, the handle is part of the wheel assembly.
