Abstract:

An air duct boot useful for connecting a heating and air conditioning duct to an air register grate to permit air to be circulated into a space to be heated or cooled. The air duct boot includes a housing of right parallelepiped configuration constructed of a synthetic resin and having an internal support for preventing excessive deflection of opposed walls of the housing when concrete is poured therearound. Reinforcing ribs are molded into the opposed walls. The housing also includes an integrally molded top or upper portion which can be quickly and easily removed after the boot is installed in a concrete pad or other foundation structure. A protuberant, generally cylindrical neck portion extends from one side of the housing near its lower end for connection to the duct. The entire air duct boot is molded as an integral unit.

Abstract:

A double air duct boot which includes a pair of identical opposed severable parts, joined through a central section. The two parts are geometrically symmetrical about the central section which joins the two parts. The central section includes a pair of identical halves joined at a central plane. The central section includes a pair of opposed segments of a cylinder constituting spaced, arcuate opposed side walls and a pair of opposed transverse walls joining the opposed arcuate side walls and lying in parallel planes. The central section is completed by a pair of elongated parallel end walls which extend perpendicular to the transverse walls to complete the closure of the central section. Each of the opposed severable parts includes a tapered riser section joined to the central section through an intermediate, optionally usable, arcuate duct mating section.
