Abstract: A pipe clamp having a pipe gripper affixed to a base is disclosed, wherein the base may selectively engage a support bar. The base includes a pair of feet and opposing clips which permit selective engagement of the pipe clamp to the support bar. The pipe clamp is initially oriented perpendicular to the support bar and a center pin is disposed in an aperture. The pipe clamp is then rotated to dispose the feet into apertures of the support bar and the clips engage the backside of the bar. The pipe gripper includes a tongue and a mating fork having a guide prong and securing prong, wherein interlocking teeth prevent displacement of the tongue from within the fork to thereby retain a pipe. The pipe is removed from the clamp through the separation of the tongue and the fork by flexing the guide prong in a radial direction so as to permit torsion of the tongue relative to the fork.

Abstract: A laundry outlet box comprises a box-like one-piece molded plastic housing having top, bottom and side walls circumscribing an axis of the box and a back wall and open front face normal to such axis. The bottom wall of the housing slopes downwardly toward the center to a drain opening and is provided at its underside with a tailpipe adaptor including coextensive radially spaced pipe-like extensions concentric with the drain opening, which extensions are adapted for selective coupling to drain pipes of different sizes. The housing is adapted to be recess mounted in a wall between vertical wall supports by interchangeable L-shape mounting brackets arranged in pairs on each side of the box with the laterally extending legs vertically spaced apart and adapted to have optionally secured therebetween electrical outlet boxes at one or both sides of the box.
