The split plastic tubing carries an electrical wire inside the tubing with sockets and bulbs extending outwardly between edges of the tubing at intervals. Stringers in the form of plastic line are connected to the base and cap as well as to the split tubing to cause the spiral coil to assume the proper shape. In addition to serving as a tree stand, the base and its cover provide a storage box in which the spiral coil and other parts of the tree are stored. The use of metal parts in proximity to electrical wires is avoided. | |
