Abstract: A device is disclosed including a compact tape measure housing enclosing a tape spool with a multi-segment spring-loaded tape retention mechanism having a tape spool, a primary rewind spring, a secondary rewind spring coupled together via a rotating spring coupling. In various embodiments, the primary and the secondary springs may be placed side-by-side making the two springs and the overall tape measure device smaller in diameter.
