Abstract: A fastener used to secure an object on a channel including a channel nut which may be entered into a slot in the channel and then turned about an axis of rotation to extend in a generally crosswise position relative to the slot for engagement of portions of the nut at locations generally adjacent opposite ends of the nut with edges of the channel. A retainer for the nut has a body and a flange integral with the body which may engage the channel at opposite sides of the channel slot for preventing the retainer from being pushed inwardly completely through the slot when the nut is turned to a crosswise position in the channel and when an object is being fastened to the channel. Resiliently deformable spring elements on the body of the retainer are so sized and arranged as to be engageable with the channel for holding the nut in its crosswise position against slippage lengthwise of the channel slot.

Abstract: A support for an electrical box, comprising a bar to be mounted between two spaced-apart wall studs or the like. The bar comprises an elongate web of sheet metal forming a front face of the bar and having side edges extending lengthwise of the bar, a pair of flanges extending rearwardly from the side edges of the web, and a forwardly-opening channel formed in the web running substantially the full length of the web between the side edges of the web.

Abstract: A support system for supporting cable tray of the type comprising a pair of generally parallel side rails interconnected by cross members. The support system comprises a series of support bars adapted to be suspended at intervals spaced lengthwise of the cable tray and with the support bars extending generally crosswise relative to the rails of the cable tray. Each support bar has a pair of rail receivers spaced apart lengthwise of the support bar for receiving the side rails of a cable tray and preventing substantial sideways shifting of the cable tray relative to the support bar. A pair of hold-down members associated with each support bar hold the rails of the cable tray in respective rail receivers of the support bar.

Abstract: A clip for securing conduit and the like to channel framing of the type comprising a pair of side flanges having outer margins formed with inwardly directed hook-shaped lips defining a slot extending lengthwise of the channel. Each lip and its corresponding flange define a recess between them extending lengthwise of the channel. The clip comprises a one-piece generally U-shaped clip member having a pair of legs with free ends. Feet at the free ends of the legs extend laterally outwardly from respective legs in opposite directions. Toes project from the feed and are spaced laterally from respective legs to define notches between the toes and respective legs. An integral protuberance projects laterally outwardly from the free end of each foot.

Abstract: A bracket for mounting an electrical switchbox or the like on a metal stud of generally channel shape having a web at one side constituting a closed side. The stud has a front and rear flange which define an open side of the stud between them. The bracket includes a bracket plate having a front end and a rear end and a flap generally adjacent the front edge of the bracket plate for attaching the bracket to the front flange of the wall stud in a position in which the bracket plate extends rearwardly adjacent one side of the wall stud. Track members generally adjacent the front end of the bracket plate hold an electrical switchbox or the like in fixed position relative to the bracket plate with one side of the box generally adjacent the bracket plate and with an open front of the switchbox facing forwardly.

Abstract: A clip for mounting an object such as an electrical box on a metal stud of generally channel shape having a web and a pair of generally parallel flanges. The clip includes a first clip part engageable with the stud for securement of the clip to the stud. The first pair has a relatively flat leg. A second clip part holds the object and has a relatively flat leg extending in generally parallel face-to-face relation with the leg of the first clip part. The leg of the second clip part is slidable relative to the leg of the first clip part lengthwise of the leg of the first clip part for adjusting the position of the object being held by the second clip part relative to the stud. Flanges define a guideway for maintaining the leg of the second clip part in longitudinal alignment with the leg of the first clip part as the leg of the second clip part is slidably adjusted relative to the leg of the first clip part.

Abstract: A support for an electrical box, comprising a bar to be mounted between two spaced-apart wall studs or the like. The bar comprises an elongate web of sheet metal forming a front face of the bar and having side edges extending lengthwise of the bar, a pair of flanges extending rearwardly from the side edges of the web, and a forwardly-opening channel formed in the web running substantially the full length of the web between the side edges of the web.

Abstract: A clip of the present invention is used for supporting conduit and like members. The clip comprises first and second resilient arms for holding a conduit or like member therebetween. The arms have outer end portions bent to extend generally toward one another. The arms are resiliently biased toward a release position in which they are spaced apart and are resiliently movable against this bias to a first support position in which the arms are closer together with their outer end portions in overlapping relation and with the arms in position to embrace a conduit or like member of a first diameter, and from the first support position to a second support position in which the arms are even closer together and in position to embrace a conduit or like member of a smaller diameter. The outer end portion of the first arm has a detent thereon. The outer end portion of the second arm is formed and configured for engagement by the detent to releasably lock the arms in their first and second support positions.

Abstract: A bracket adapted for mounting an electrical box on a wall stud having a front face, a rear face and opposite sides. The bracket comprises a bracket plate having a front end, a rear end and a length not substantially less than the depth of the wall stud in front-to-rear direction. Ears adjacent the front end of the bracket plate are provided for attaching the bracket to the front face of the wall stud in a position in which the bracket plate extends rearwardly across one side of the wall stud from a position generally adjacent the front face of the wall stud to a position generally adjacent the rear face of the wall stud. The bracket includes tongues for affixing an electrical box to the bracket in a position wherein one side of the box is engageable with the bracket plate with the box extending in cantilever fashion laterally outwardly from the bracket plate away from the wall stud.

Abstract: A system for positioning and supporting a pipe or conduit in fixed position relative to a structural element, comprising a support bar to be secured to the structural element having openings therein spaced at regular intervals lengthwise of the bar, and a thin flat bracket member to be affixed to the support bar in a selected position lengthwise of the bar. The bracket member is formed with at least one L-shaped lug and is adapted to be inserted through a selected opening of the support bar and moved relative to the bar from a preliminary position to a final position wherein the lug extends beyond the opening and overlaps the bar with a marginal edge portion of the opening received in the space between the lug and the bracket member.
