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 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.
