An improved device for securing a structural member to a generally U-shaped longitudinally extending channel member is set forth. A bridge section connects together two generally parallel sidewall sections with the sidewall sections each having a respective lip which extends inwardly laterally towards the other sidewall section and bends towards and ends a spaced distance from the bridge section. A first nut has oppositely extending lateral arms which are adapted for positioning beneath and are engageable with the lips. A bolt can be threaded into a threaded opening in the nut. The improvement is a support member positionable between the bridge section and the lips and between the sidewall sections. The support member has a pair of lateral sides, each positionable adjacent and facing a respective one of the sidewall sections. It also has a pair of ends alignable along the channel member. The support member defines a cavity generally orthogonal to the lateral sides and to the ends. The cavity is positionable in facing relation to the lips. It is adapted to retain the nut with its lateral arms beneath the lips. The support is prevented from rotating sufficiently to align the lateral sides along the channel member.
