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 interior 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.

An electrical raceway assembly including a substrate engaging member having an upper region, an intermediate region, a lower region, an inner surface and an outer surface; a signage engaging member having an upper region, an intermediate region, a lower region, an inner surface and an outer surface; wherein the upper region of the substrate engaging member and the upper region of the signage engaging member are releasably secured to each other; and wherein the lower region of the substrate engaging member includes a segment that regulates positioning of the lower region of the signage engaging member.

An electrical gang box adapted for use with drivers is disclosed. The electrical gang box includes a main compartment with a front opening sized and adapted to accept an electrical control and structure around the front opening to secure the electrical control within the front opening and within the main compartment. The electrical gang box also includes a lower compartment that extends below the main compartment, is set back from the front of the main compartment and is open to the main compartment along an upper portion. The gang box may also include one or more pairs of rails disposed on opposite interior walls. In such cases, a divider panel is sized to slide into and extend between the rails to divide the junction box. Multiple-gang boxes with these features are also disclosed.

A panel mount for supporting an electronic device at a hole in a control panel and mountable with access to only the front of the panel. It has a housing that slides into a tubular elastomeric grommet. During installation, an expander segment of the housing slides within a bulging segment of the grommet to expand the grommet inward of the hole and for retaining the components within the hole. A tubular male pre-assembly segment on the exterior surface of the tubular housing permits the housing to be pre-inserted partially into the grommet without expanding any part of the grommet radially outward in preparation for inserting the assembled housing and grommet into the panel hole. A withdrawal lock prevents the housing from sliding axially out of the grommet after installation. The withdrawal lock includes a shoulder formed on the grommet and a shoulder formed on the housing.

Cabling device for a fence with posts (6), wherein the cabling device comprises several duct elements (1, 2) which are provided to form a first duct which connects to one side of the fence and into which cables (14) extend, wherein these duct elements (1, 2) comprise linear duct elements (1), which are provided to extend between two posts (6) and adapting duct elements (2) which are provided to connect adjacent linear duct elements (1) which are separated by a said post (6), by extending around the said post (6).

According to one aspect, an electric power distribution module comprises a housing having an opening. A substrate is disposed in the housing and an electrical conductor is disposed on the substrate. An edge portion of the substrate proximate the opening is adapted to receive and electrically connect a connector from outside the housing through the opening to the conductor.
