Abstract

A chalk line device includes a housing, a spool, a chalk line, a hook, and a cap. The housing defines an outer surface and an internal chamber, and the housing includes an opening. The spool is supported in the internal chamber for rotation relative to the housing. The chalk line extends through the opening of the housing and the chalk line includes a first end and a second end. At least a portion of the chalk line is wrapped around the spool. The hook is secured to the first end of the chalk line and includes a tip adapted to engage a work piece. The cap is removably coupled to the housing to cover the opening. The cap includes a nozzle through which the chalk line extends and a projection for engaging and releasably securing the hook against the cap.
