Abstract
A chalk line device includes a housing and a chalk line stored in the housing. The chalk line terminates in a hook at one end and the hook is disposed outside of the housing. The housing may include a side wall with a depression formed therein that is shaped to receive the hook for storage. The depression has an edge that allows the hook to securely engage. The housing may also include a translucent window for allowing the user to check the level of chalk in the chalk line device. The translucent window forms at least a portion of a wall of the housing. The translucent window can be made, for example, of a plastic and can be integrally formed with the housing.
