Abstract: A ceiling of filter panels is supported by support rods that extend through corner intersection of adjacent panels, and by a supporting disk secured to the lower end of the rods to support the corners of the filter panels. The disk has a notch in it that mates with the filter corner so that with the disk rotated to a position wherein the notch is aligned with the panel corner, a panel may be installed or removed from the assembly. Once a panel is in position, the disk is rotated about 45.degree. to a position wherein it supports a portion of the corner of each filter panel at that intersection. Retracted pins in the support disk are then threaded further into the disk so that the pins extend into an aligned hole in the corner of each panel at that intersection to align the panels. Sealing strips carrying sealing gel are then positioned around the periphery of the panels to span the gap between adjacent panels, with the strips being supported by the edges of the panels.

Abstract: A plurality of spaced, rigid support pedestals that are vertically adjustable are employed to support manufactured buildings. The pedestals have a truncated pyramid or frusto-conical shape to provide both lateral and vertical support for the manufactured building. An adjustable connector between the base of the pedestal and the upper end allow the height of each pedestal to be independently varied to support the manufactured home in a dead level position. The upper ends of the support pedestals are clamped to the flanges of I-beams of the building chassis so as to prevent the building from shifting relative to the foundation.

Abstract: A plurality of spaced, rigid rectangular frames that are vertically adjustable are employed to support manufactured buildings. The frames are formed of pedestals interconnected by vertical trusses. The upper ends of the frames, above the support pedestals are clamped to the flanges of I-beams of the building chassis so as to prevent the building from shifting relative to the foundation.
