Abstract: A tubular reducer fitting for transitioning from an existing electrical nonmetallic tubing socket of one size to an electrical nonmetallic tubing socket of a smaller size. The male end portion has a cylindrical outer surface with a pair of axially-spaced projections extending outwardly therefrom and is receivable in an existing electrical nonmetallic tubing socket. The female end portion has an electrical nonmetallic tubing socket therein. The male end portion is configured for locking reception in a first trade size electrical nonmetallic tubing socket and the opposite female connector end portion has a smaller trade size electrical nonmetallic tubing socket herein.

Abstract: A suction cup located on an axis has axially opposite front and rear ends. The front end is configured to adhere to a window pane by suction. A post extends along the axis rearward from the rear end and has axially spaced grooves. A bracket is configured to be mounted in any one of the grooves and to hold an item a set distance rearward from the post.

Abstract: A wire management box is sized to contained a high voltage plug and a low voltage terminal inward of a building wall surface. The box has an access opening that is sized for a user manually to reach through with the plug and the terminal. The box further has a high voltage wall that supports a high voltage outlet in an installed position spaced inward from the access opening, and a low voltage wall that supports a low voltage receptacle in an installed position spaced inward from the access opening adjacent to the outlet.

Abstract: A knockout in a sidewall of a plastic electrical box has a slot for receiving a screwdriver tip to apply a knockout force to the knockout. The slot is located adjacent the box bottom wall to minimize deformation of the sidewall by a knockout force.

Abstract: A bracket for supporting electrical nonmetallic tubing has axially aligned large and small spring clips for receiving and retaining large and small diameter tubing. A plurality of side-by-side pairs of the spring clips are arranged with the large and small spring clips in one pair reversely positioned relative to the large and small spring clips in an adjacent pair. Some clips are configured for attaching ties thereto that extend over a tube to hold the tube in the clip. The bracket has support legs for engaging a support surface, and fastener receiving extensions for attaching the bracket to the support surface.

Abstract: An electrical box having spring legs for supporting the box within a space between a pair of spaced-apart parallel concrete forms. The legs engage the inside surface of one form and bias the open end of the box against the inside surface of the other form. The legs and the bottom of the box are cooperatively configured to facilitate attachment of the legs to the box. A bendable strap is attached to the box for wrapping around reinforcing bars within the forms. The legs and strap hold the box in position when concrete is poured into the space between the forms. The entire box and support elements remain embedded within the finished concrete wall, and with the open end of the box exposed at an outer surface of the concrete wall.

Abstract: A fitting for attaching ENT tubing to a concrete form has an inverted cup-like configuration with a bottom opening and an internal cavity within a fitting wall. A flange extends outwardly from the fitting wall around the bottom opening and has fastener-receiving holes for attaching the fitting to a plane surface of a concrete form. A socket extends through the fitting wall into the cavity for receiving an end portion of an ENT tube. The socket has a plurality of circumferentially-spaced resilient fingers that are inclined inwardly toward the socket axis for gripping an ENT tube. A pair of opposite fingers have teeth that are receivable in an annular groove in an end portion of a corrugated ENT tube. The teeth have rounded ends to facilitate ratcheting movement of the ENT tube end portion both into and out of the socket.

Abstract: An electrical outlet box molded of plastic material has a knockout arrangement in a box wall that is formed by inner, intermediate and outer circular grooves that are eccentrically positioned to overlap at a tangent location and define inner, intermediate and outer eccentrically positioned circular knockouts. The grooves vary in depth from a minimum depth at the tangent location to a maximum depth opposite from the tangent location. Areas of increased weakness are provided in the box wall at the bottoms of at least the inner and intermediate grooves, and screwdriver slots are provided in the knockouts opposite from the tangent location.

Abstract: A square electrical box molded in one-piece of plastic material has three ENT connectors extending outwardly from each box sidewall. The connectors on each sidewall include a middle connector and two outer connectors. All of the middle connectors are sized for receiving one-half inch standard trade size ENT conduit. Both of the outer connectors one pair of opposite sidewalls are sized for receiving three-quarter inch standard trade size ENT conduit. The other pair of opposite sidewalls have one outer connector sized to receive three-quarter inch standard trade size ENT conduit and another outer connector sized to receive one-inch standard trade size ENT conduit. The box has attachment ears extending outwardly from the box corners along diagonal lines that extend across diagonally opposite ones of the box corners. An adapter attached to a front surface of the box has attachment ears aligned with the box ears.

Abstract: A square electrical box molded in one-piece of plastic material has three connectors extending outwardly from each box sidewall for receiving different sizes of electrical nonmetallic tubing. The box internal corners are occupied by bosses that extend the full height of the corners and have fastener receiving holes therein. Attachment ears extend outwardly from the box, and an adapter attachable to a front surface of the box has attachment ears aligned with the box ears. Fastener receiving holes through the ears are configured to receive fasteners that are inwardly inclined toward the box central longitudinal axis.

Abstract: An electrical outlet box having alternative mounting flanges on opposite sides thereof for selectively mounting the box to a front surface of a wall stud or to a side surface of a wall stud. The box and mounting flanges are configured for use of either mounting flange with the box located on either of opposite sides of the wall stud.

Abstract: A joist has a front surface and first and second opposite side surfaces. The side surfaces extend in a rearward direction from the front surface. They also extend in a lateral direction perpendicular to the rearward direction. An electrical box has a hole configured to receive a fastener that fastens the box to the first side surface. The box further has a side wall and a rear wall together defining a cavity that is isolated by the box from the hole. The cavity is configured to extend along both side surfaces of the joist and to contain electrical connections. The side wall extends laterally beyond the hole and the rear wall is located rearwardly beyond the hole.
