摘要: A chalk line holder comprises a housing having a partition dividing the housing into two compartments. Each of a pair of substantially coaxially mounted spools is rotatably mounted in a corresponding one of the compartments. A chalk line of a first desired color is wound on one of the spools and a chalk line of a second desired color is wound on the other spool. Coupling devices are provided in the spools for selectively coupling a shaft for rotating the spools to a desired one of the spools for separate rotation. A handle outside the housing is coupled to the shaft for manually rotating the spools.
