ABSTRACT:
A register opening cover may be used to cover register openings until the register boot is installed in the register opening. During the installation of the register boot, the invention may be used to hold the register boot in place until the register boot is securely connected to the floor. After the register boot is installed, the cover forms an insulator around the register boot. One embodiment of the invention provides a register opening cover and register boot frame that can be configured to fit register boots of different sizes. Another embodiment of the invention provides a register opening cover that will support some of the weight of a worker who may step on the covered register opening.
