A flexible line storage device with a case bounding a storage space for a supply of flexible line. The case has a peripheral wall extending around a central axis and first and second axially spaced walls. The peripheral wall has a radially inwardly facing surface that, in conjunction with axially oppositely facing surfaces on the first and second walls, bounds the storage space. The first wall has a first opening through which the central axis extends. An adaptor on the first wall at least partially blocks the first opening and defines a passage through which line in the storage space moves as the line is drawn out of the storage space.
