ABSTRACT:
A multi-line chalk reel is disclosed that may be comprised of three or more line reels disposed in a polar arrangement of parallel but distinct rotation axes that has a single method for engaging and disengaging a single drive arrangement to any one spool. This arrangement provides a variety of advantages, including a package solution of useful dimensions and a low part count to minimize parts in assembly. The single drive arrangement reduces cost, and provides for convenient access to individual spools.
