A pool cover assembly for covering a swimming pool includes a cover, a pool cover box, and a reel positionable within the pool cover box and configured for carrying the cover. The reel includes a tube and an end piece. The tube includes an end with at least one keying feature and the end piece includes at least one mating keying feature. The keying feature and the mating keying feature coact to allow relative axial movement between the tube and the end piece, but not allow relative rotational movement between the tube and the end piece.
