Abstract
A method of drawing lines into a housing includes: rotating a dial in a first rotational direction of the dial such that a first spool located in an interior of the housing is mechanically rotated in a first rotational direction thereby winding a first line thereabout; and rotating the same dial in a second rotational direction opposite to the first rotational direction such that a second spool located in the interior of the housing is mechanically rotated in a first rotational direction thereby winding a second line thereabout. The rotating of the same dial in the second, opposite rotational direction does not result in unwinding of the first line from the first spool, and the rotating of the same dial in the first rotational direction does not result in unwinding of the second line from the second spool.
