    [0014]FIGS. 1-4 show a bracket 10 for supporting electrical devices. The bracket 10 includes an elongated first portion or flange 22 , and a pair of second portions 26 connected to the flange 22 . The flange 22 is oriented in a first plane and extends around an opening 30 . In the illustrated embodiment, the flange 22 has a rectangular shape and includes a pair of end portions 34 and a pair of side portions 38 extending between the pair of end portions 34 . Each end portion 34 may include holes 42 ( FIG. 2 ) for coupling the flange 22 to a stud 50 ( FIG. 7 ). A longitudinal axis 14 of the bracket 10 extends between the end portions 34 .
    [0015]Each second portion 26 is positioned within the opening 30 . The second portion 26 includes a first leg 58 connected to one of the side portions 38 of the flange 22 and a second leg 62 coupled to the first leg 58 . As best shown in FIG. 3 , the second legs 62 are oriented in a second plane offset from the first plane of the flange 10 . Apertures 68 for mounting an electrical device (e.g., electrical box 70 and mud ring 72 — FIG. 6 ) are formed on each second leg 62 . As best shown in FIG. 2 , the apertures 68 may be formed as keyhole apertures having a round hole 74 and an elongated slot 78 extending laterally from the round hole 74 .
    [0016]As shown in FIG. 2 , in the illustrated embodiment the apertures 68 are aligned in a longitudinal direction and extend along a portion of the second leg 62 between the end portions 34 of the flange 22 . One of the second portions 26 a may include an aperture 68 a positioned adjacent one of the flange end portions 34 a , with the other apertures 68 a positioned sequentially along a portion of the second leg 62 a . The other second portion 26 b may include an aperture 68 b positioned adjacent the opposite end portion 34 b of the flange 22 , with the other apertures 68 b positioned sequentially along a portion of the other second leg 62 b , such that the apertures 68 b extend from alternate end portions 34 . The apertures 68 provide multiple positions at which an electrical box 70 and mud ring 72 may be attached.
    [0017]FIG. 5 shows a blank 82 before the bracket 10 is formed. The second portions 26 are initially formed coplanar with the flange 22 and are subsequently bent into the opening 30 . In the illustrated embodiment, each second portion 26 is bent such that the second leg 62 is connected to the first leg 58 by a longitudinal channel 86 ( FIG. 3 ) extending along the length of the second portion 26 . The channel 86 provides additional rigidity. In some embodiments, the channel 86 also assists in centering or locating the electrical box 70 ( FIG. 6 ) with respect to the bracket 10 .
    [0018]FIGS. 7-9 show the bracket 10 coupled between two support members or studs 50 , and three electrical boxes 70 and three mud rings 72 are secured to the bracket 10 in multiple locations. It is understood that, in some embodiments, a different number of electrical boxes 70 and mud rings 72 may be secured to the bracket 10 , and the electrical boxes 70 and mud rings 72 may be secured in other locations. That is, the boxes 70 and mud rings 72 may be secured to the bracket 10 at positions between the boxes 70 and mud rings 72 shown in FIG. 7 .
    [0019]In the illustrated embodiment, fasteners 90 extend through the holes 42 in each flange end portion 34 and into one of the studs 50 . As shown in FIGS. 9 and 10 , the end portions 34 are positioned between the studs 50 and a wall material 94 (e.g., drywall— FIGS. 8 and 9 ). Electrical boxes 70 ( FIG. 8 ) are positioned adjacent one side (e.g., a rear side) of the second portion 26 , and mud rings 72 ( FIG. 7 ) are positioned adjacent an opposite or forward side of the second portion 26 . in the illustrated embodiment, the electrical boxes 70 are secured to the second portion 26 via fasteners 98 clamping onto an edge of the second leg 62 . The offset between the plane of the second legs 62 and the plane of the flange 22 allows the mud rings 72 to be recessed relative to the wall 94 , so that a front face of the mud ring 72 is positioned at a desired depth relative to the outer surface of the wall 94 . In the illustrated embodiment, the box 70 is a 4-inch box.
    [0020]FIG. 11 illustrates another embodiment in which each electrical box 70 is secured to the second portion 62 by fasteners 98 extending through the apertures 68 of the second legs 62 . The fasteners 98 may be inserted through the round hole 74 of the mounting apertures 68 and then slid along the elongated slot 78 until the electrical box 70 is in a desired position. FIGS. 12 and 13 illustrate another embodiment in which each mud ring 72 is secured to one of the electrical boxes 70 by fasteners 98 (e.g., box screws) extending through the opening 30 of the bracket 10 . The fasteners 98 are tightened such that the boxes 70 and mud rings 72 are clamped onto opposite sides of the second leg 62 . As shown in FIG. 13 , the channel 86 assists in centering each electrical box 70 in a vertical direction (i.e., aligning the electrical box 70 with a longitudinal axis of the bracket 10 ). In the embodiment shown in FIG. 13 , the box 70 is a 4 11/16″ box.
    [0021]FIGS. 14-17 illustrate a bracket 210 according to another embodiment. The bracket 210 is similar to the bracket 10 described above with respect to FIGS. 1-13 , and for the sake of brevity only differences are described herein. Similar features are identified with similar features, plus 200 .
    [0022]As shown in FIGS. 14 and 15 , each second leg 262 includes tabs 264 extending into the opening 230 . In addition, the bracket 210 includes apertures 268 having various shapes. For example, some mounting apertures include opened ended slots 268 a formed along edges of tabs 264 on one of the second portions 226 , and keyhole slots 268 b formed at an angle relative to tabs 264 on an opposite side of the bracket 210 . Additionally, joined mounting apertures 268 c may be formed on each second leg 262 and may be formed as two key hole slots positioned in mirrored relationship in which the elongated slot portions are joined to one another.
    [0023]FIG. 18 shows a blank 282 before the bracket 210 is formed. The second portions 226 are initially formed coplanar with the flange 222 and are subsequently bent into the opening 230 . Each second portion 226 is bent such that a second leg 262 is connected to a first leg 258 by a longitudinal channel 286 ( FIG. 16 ) extending along the length of the second portion 226 . The channel 286 provides additional rigidity and assists in locating the electrical boxes 70 ( FIGS. 20 and 21 ) and mud rings 72 along a centerline of the bracket 210 .
    [0024]FIG. 19 illustrates the bracket 210 coupled between two studs 50 . Electrical boxes 70 and mud rings 72 are secured to the bracket 210 in multiple locations. The boxes 70 and mud rings 72 may be coupled to one another by one or more fasteners 98 , and threading the fasteners may cause the boxes 70 and mud rings 72 to clamp or exert a compressive force on the second portion 226 . In some embodiments, the fasteners 98 may engage at least an edge of the second portion 226 . In some embodiments, the apertures 268 may provide multiple fixed or discrete positions at which the box 70 and mud ring 72 may be secured. In the illustrated embodiment, the electrical boxes 70 are secured by fasteners 98 extending through the slots 268 a , 268 b formed on the tabs 264 , and the mud rings 72 are secured via the same fasteners 98 , FIG. 20 shows the electrical boxes 70 secured to the second portion 226 by fasteners 98 (e.g., screws) extending through a center of the bracket 210 . FIG. 21 shows the electrical boxes 70 secured to the second portion 226 by fasteners 98 (e.g., screws) extending through the joined mounting apertures 268 c.
    [0025]FIGS. 22-26 illustrate a bracket 410 according to another embodiment. The bracket 410 is similar to the bracket 10 described above with respect to FIGS. 1-13 , and for the sake of brevity only differences are described herein. Similar features are identified with similar features, plus 400 .
    [0026]As shown in FIGS. 22 . and 23 , the bracket 410 is formed as two separate members 420 a , 420 b slidably engaging one another. In the illustrated embodiment, the side portions 438 of the flange 422 and the second portions 426 of each member 420 a , 420 b overlap the side portions 438 and second portions 426 of one another and permit sliding movement relative to one another. One side portion 438 a of the first member 420 a is received within an associated side portion 438 b of the second member 420 b , while the other side portion 438 b of the first member 420 a receives the other side portion 438 b of the second member 420 b . The slidable connection between the members 420 a , 420 b permits the length of the bracket 410 to be adjusted to accommodate varying distances between adjacent studs. As shown in FIGS. 27 and 28 , in the illustrated embodiment, the members 420 a , 420 b are identical to each other. Although not shown in FIGS. 22-28 , the second portion 426 of each member 420 a , 420 b may include apertures for securing electrical boxes and mud rings to the bracket 410 .

Additionally, joined mounting apertures 668 c may be formed on each second leg 626 and may be formed as two key hole slots positioned in mirrored relationship in which the elongated slot portions are joined to one another.
    [0029]FIG. 33 shows a blank 682 before the bracket 610 is formed. The second portions 626 are initially formed coplanar with the flange 622 and are subsequently bent into the opening 630 . Each second portion 626 is bent such that a second leg 626 is connected to a first leg 658 by a longitudinal channel 686 ( FIG. 31 ) extending along the length of the second portion 626 . The channel 686 provides additional rigidity and assists in locating the electrical boxes 70 ( FIG. 34 ) and mud rings 72 along a lateral centerline of the bracket 610 .
    [0030]FIGS. 34 and 35 illustrate the bracket 610 coupled to a stud 50 . An electrical box 70 and mud ring 72 is secured to the bracket 610 . In the illustrated embodiment, the electrical box 70 is secured by fasteners 98 extending through apertures 668 a , 668 b formed on the tabs 664 , and the mud rings 72 are secured via the same fasteners 98 . FIG. 36 shows the electrical boxes 70 secured to the second portion 626 by fasteners 98 (e.g., screws) extending through the joined mounting apertures 668 c . FIG. 37 shows the electrical boxes 70 secured to the second portions 626 by fasteners 98 (e.g., screws) extending through a center of the bracket 610 . FIGS. 38 and 39 illustrate a pair of brackets 610 coupled to a common stud 50 , with one bracket 610 positioned on each side of the stud 50 .
