Abstract: A retractable reel assembly comprises double tear drop shaped housing, a spool disposed in the housing and journaled for rotation about an axis, the spool and housing defining a plurality of chambers within the housing around the axis. The spool and housing define a cable storage chamber with a second length of cable retractably stored therein and a cable expansion chamber with a length of cable stored therein, a spring chamber and a ratchet chamber. The housing also has a spring takeup compartment and cable adjustment compartment located on a second parallel axis. A constant force spring extends from the spring storage chamber to the spring takeup compartment to urge the spool to rotate in a cable retracting direction.
