The present invention relates to a tape measure assembly having an internal deployment warning system therein. The device includes a substantially hollow housing having a top wall, a bottom wall, an end wall and a front wall with a horizontal slot between the front wall and the bottom wall. A tape measure having a plurality of marking indicia thereon extends through the horizontal slot and is selectively retractable within and extendable from the housing interior using conventional means currently used in various tape measuring devices. A first magnet is attached to the bottom wall of the housing for securing the housing to a metallic surface. A second magnet is removably attached to the top wall of the housing and has a slit thereon for selectively receiving an L-shaped catch member at a first end of the tape measure. Received within the housing adjacent an edge of the tape measure is a spring biased ratcheting pawl for selectively engaging a plurality of longitudinally aligned apertures proximal a second end of the tape measure. Accordingly, when the tape measure has been extended to a predetermined length, the ratcheting pawl will emit a clicking noise thereby audibly alerting a user that the tape is approaching its maximum length.
