A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base by a bottom clip. A first tube engages the base's top to clamp a funnel shaped, diaphragm seal to the base. The first tube has spaced, radially extending, parallel ridges at predetermined distances from the base. Longitudinal channels separate the ridges. An extension tube has inward extending lugs passing along the channels to engage various ridges when rotated to fix the passage length. The extension engages the base bottom for corrugated deck supports. A cap with repositionable, locating filaments closes either tube.

A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base. First and second, spaced apart, funnel shaped, diaphragm seals are connected to a first tubular passage or an adjustable length tubular extension. A cap for closing either tube has an inclined outer surface to form a beveled entrance to the passage in the concrete. An aerator box may be connected to the base. Hinged ends on the base allow the shape and length of support to be altered.

A mounting bracket is provided for mounting pipes between studs of a building. An elongated support member has two elongated sides generally perpendicular to each other and has opposing ends adapted to fasten the support member to studs of a building. A locking bracket encircles the support bracket. The locking bracket has four segments comprising a first base segment, a second flange segment, a third intermediate segment and a fourth distal segment. A flexible hinge line is formed at least between the flange and intermediate segment. The base segment and flange either abutting or are close to adjacent sides of the elongated support member during use with the intermediate segment spanning the distal edges of the sides of the support member. The fourth distal segment overlaps and nests with the first base segment to restrain motion in the plane of the base segment. A latch mechanism restrains the projection from disengaging. The projection is preferably forced against the support member by the latch mechanism.
