A register box for an HVAC installation has a body with a plurality of side panels arranged in a generally rectangular or square configuration and a wall extending in generally transverse relation to the plurality of side panels, and an expandable polymeric material affixed to an inner side of the side panels and across the wall. The wall has a plurality of concentric circular areas cut into the wall. Each of the concentric areas is formed of a first partial circle having ends in spaced relation to a second partial circle. The circular area can be removed from the wall so as to allow a user to cut through the polymeric material at the wall so as to form a hole opening to an interior of the register box. This hole can receive a collar therein. The collar can be connected to the HVAC system.

LOCATING COLLAR FOR INSULATED REGISTER BOX

A process for forming an insulated register box includes forming an insulation across the interior surface of a register box, placing a locating collar onto an outer surface of the register box, marking the outer surface of the register box so as to present a representation corresponding to an inner diameter of the collar, separating a portion of the outer surface of the register box from a remainder of the register box corresponding to the marked representation, penetrating the exposed insulation with the collar until an end of the collar opens to an interior of the insulated register box, and positioning the flange against the outer surface of the register box.

PROCESS FOR FORMING A REGISTER BOX THAT IS ADAPTABLE TO DUCTWORK OF AN HVAC SYSTEM
20230194121 · 2023-06-22 ·

A process for forming a register box has a body formed with a plurality of side panels arranged in a generally square or rectangular configuration with a wall extending transverse to the side panels. A plurality of circular areas are cut into the wall. An expandable polymeric foam material is introduced into an interior of the body. The body is positioned in a fixture such that the wall is juxtaposed against a surface of the fixture. A plug is inserted into the interior of the body. The expandable polymeric foam material is expanded in the interior of the body such that the expandable polymeric foam material solidifies across the wall and around the plug. The plug is then removed from the body and the body is then removed from the fixture.
