Claim 1:
2. A panel assembly for installation onto a first track beam including a first beam flange having a first non-linear edge, the panel assembly comprising:
a panel having an upper surface and a lower surface that opposes the upper surface; and
a lockable catch moveably connected to the panel and in contact with the lower surface of the panel, the lockable catch including a lockable mating edge configured to selectively mate with the first non-linear edge of the first beam flange of the first track beam, and a lockable catch edge extending beyond the lockable mating edge;
wherein the lockable catch is moveable on the lower surface of the panel between an unlocked position and a locked position;
wherein the lockable catch edge translates toward the first non-linear edge of the first beam flange based on the lockable catch moving from the unlocked position to the locke d position;
wherein when the lockable catch is in the unlocked position, the lockable catch edge is retracted away from the first non-linear edge of the first beam flange sufficiently for the panel to be seated on the first track beam; and
wherein when the lockable catch is in the locked position, the lockable mating edge mates with the first non-linear edge of the first beam flange and the lockable catch edge retains the panel on the first track beam with the upper surface and the lower surface in a horizontal orientation; and
a key configured to transition the lockable catch from the unlocked position to the locked position.
