Abstract: A meter box with insulation-piercing wire termination connectors is disclosed. Each connector includes a conductor receiver having an inner surface that defines a channel sized to receive an electrical power conductor comprised of a conductive wire encased within insulation. At least one protrusion projects from the inner surface of the conductor receiver into the channel and has a continuous edge spaced apart from the inner surface that is positioned to pierce the insulation and electrically contact the conductive wire when the electrical power conductor is clamped within the conductor receiver. Each connector may also include a meter jaw configured to receive a connector blade of an electric meter, wherein the meter jaw is mechanically and electrically connected to the conductor receiver.

Abstract: Channel framing includes an elongate body having a longitudinal axis and defining an interior extending along the longitudinal axis. The body includes a first side defining a continuous slot extending lengthwise of the body and into the interior of the body. A second side is generally opposite the first side and defines a fitting groove extending lengthwise of the body. The fitting groove is configured for receiving at least one type of fitting to secure the fitting to the channel framing.

Abstract: A fitting for channel framing includes a first clip arm configured to extend into a first external fitting groove of the channel framing and clip onto the channel framing, and a second clip arm configured to extend into a second external fitting groove of the channel framing and clip onto the channel framing. An outer portion connected to and extending between the first and second clip arms is configured to span across the continuous slot when the first and second clip arms extend into the respective first and second external fitting grooves and are clipped onto the channel framing.

Abstract: A fastener nut for securing a part to channel framing defining at least one internal, generally T-shaped track extending lengthwise of the channel framing. The fastener nut includes a nut body, and first and second wings extending longitudinally outward from respective first and second longitudinal ends of the body. The first and second wings having respective terminal ends defining an effective wing span therebetween that is greater than the length of the body such that at least a portion of the fastener nut has a generally T-shaped side profile. The fastener nut is insertable in the generally T-shaped track of the channel framing to allow the fastener nut to slide along the length of the channel framing and to restrict transverse movement of the fastener nut in the interior, relative to length of the framing, for use in positioning the fastener nut along the channel framing.

Abstract: A conduit clamp for securing a conduit component to channel framing includes first and second jaws each having opposite first and second end portions. The first end portions of the first and second jaws are configured for securement to one another, such that first and second jaws generally oppose one another and the second end portions of the first and second jaws are free from attachment to one another, to define a conduit receiving space between the first and second jaws. Each of the first and second jaws includes a coupling component at the second end portion thereof having a generally dovetail shape configured for reception in an external fitting groove of the channel framing to attach the conduit clamp to the channel framing.

Abstract: A fitting for channel framing includes a coupling component and a washer secured to the coupling component. At least a portion of the coupling component has a generally dovetail cross-sectional shape configured for reception in an external fitting groove of the channel framing. The washer engages outside surfaces of a second side of the channel framing at opposite sides of the external fitting groove when the coupling component is received in the external fitting groove.
