ABSTRACT:
An indoor mail slot cover that can be weather-stripped is provided to prevent heat loss through mail slots. The mail slot cover has a cover flap, separable hinge sections connected to the cover flap and separable lug sections connected to the hinge sections. In a preferred embodiment the cover flap, lug sections and hinge sections can be formed from a rectangular plastic plate. The plate is provided with grooves, which form the hinge and lug sections in the plate and which permit portions of the cover flap, hinge sections and lug sections to be broken off and discarded to thereby reduce the size of the mail slot cover in accordance with the size of the mail slot. An adhesive ferrite strip and an adhesive magnetic strip arrangement can be provided to secure the cover flap in a closed position. Attachment tabs can additionally be provided to secure the mail slot cover to the building structure.
