    摘要: A preferred foot traffic grid has a plurality of grid sections including an initial grid section, a terminating grid section, and a plurality of intermediate grid sections therebetween. Adjacent grid sections are coupled using a pair of spaced connectors received in corresponding channels in the adjacent connector. The channels and connectors are positioned on opposed sides of a support leg.

    摘要: The invention is directed towards a furnace comprising a panel and filter assembly. At least two z-shaped brackets and two flanges are used to retain a filter directly behind the front panel of the furnace. This allows for easy removal and installation of filters in the furnace. It further allows for the use of commercially available disposable filters.
