Abstract
A modular attic walkway system for creating a walkway across attic joists which includes a plurality of attic joists each has a top face. A plurality of platforms is removably attached to the top faces such that each platform traverses between adjacent attic joists. Each of the platforms is releasably interlocked with an adjacent one of the platforms. Each platform includes a panel. The panel has a top surface, a bottom surface, and a perimeter surface which extends between the top and bottom surfaces. The perimeter surface includes a first mating edge, a second mating edge, a first lateral edge, and a second lateral edge. The first mating edge includes a tongue cutout which extends inwardly from the first mating edge toward the second mating edge. A tongue extension extends outwardly away from the second mating edge and releasably interlocks with a tongue cutout of an adjacently positioned panel.
