Abstract
A skylight with a modular shaft. The skylight includes a curb surrounding an opening formed in a roof. The curb defines a downwardly opening channel with at least one serrated wall to receive the modular shaft. The modular shaft extends from the curb to an opening formed in a ceiling and includes a number of panels secured to one another by a number of corner connections. A hook with at least one serrated wall is mounted to each of the panels. The hooks fit into the channel such that the serrated walls contact one another and secure the shaft to the curb by a ratcheting effect.
