ABSTRACT:
An attic access apparatus comprises an access frame with sidewalls extending upward from a flange member and configured to extend upward into an attic opening between structural members forming the attic opening. A recessed groove along inner surfaces of the sidewalls is configured such that fastening screws can be located in the groove. A trim flange extends outward from the sidewall to cover fasteners used to fasten the ceiling to the bottom of the structural members, and a support flange extends inward from the sidewalls to form a support flange. An insulated lid drops into the access opening formed by the inner surfaces of the sidewalls and rests on the support flange, and a seal member provides a seal between the lid and the access frame to prevent air movement between the lid and access frame.
