ABSTRACT:
A chalk line reel having a housing and a closure assembly. The housing has a storage space for a supply of chalk and a spool around which a supply of flexible line can be wrapped. The housing further has a wall with a fill opening therethrough in communication with a storage space. The closure assembly selectively a) blocks the fill opening to confine chalk in the storage space and b) exposes the fill opening to allow introduction of chalk from a supply thereof through the fill opening into the storage space. The closure assembly has a body that is engaged with the housing wall so as to substantially fully block the fill opening with the body in an operative position, and is repositionable from the operative position into a second position wherein the fill opening is exposed. The body has a graspable tab that can be engaged by a user to facilitate repositioning of the body from the operative position into the second position.
