A reusable spool for use in installing electrical wiring is provided. The spool may include first and second mating halves, each having an end plate and a central mandrel. The mandrel of one half may be inserted into a wound coil of wire, which can then be overturned to allow the second half to be connected to the first half. The first and second halves may be joined through a plurality of arcuate longitudinal tabs which slidably engage in one position to adjust width, and upon rotation, lock frictionally into a given position.
