Structural glazing systems for skylights which are designed to facilitate installation, maintenance and replacement of skylight panels from inside a host structure. The internal fastening apparatus of the structural glazing systems include multiple, open-chamber carrier beams which are interconnected in a lattice or grid configuration and are each shaped to receive a pair of parallel, spaced bottom glazing strips for receiving the bottom edges of separate glass or plastic skylight panels. Companion exterior glazing caps each carry a pair of spaced top glazing strips for seating on the top edges of the skylight panels. The exterior glazing caps are shaped to facilitate bolting to the carrier beams and securing the glass or plastic skylight panels in position between the top and bottom glazing strips. A carrier beam closure is designed to removably close the open chamber of each hollow carrier beam and to facilitate concealment of, and access to, the multiple cap bolts which are used to bolt the carrier beams to the corresponding exterior glazing caps, respectively. A system of condensate gutters is provided on the carrier beams, which gutters meet at the points of intersection of the carrier beams to carry condensate away from the glass or plastic panels.
