Abstract
A telescoping ladder includes a stabilizer connected to a stabilizer housing proximal to the floor surface on which the ladder is positioned. The first stabilizer can move between an extended position and a collapsed position. In the extended position, the first stabilizer extends out of a hollow body portion of the stabilizer housing and collapse into the hollow body portion of the rung in the collapsed position. The stabilizer comprises a locking button to lock the stabilizer in its extended position. The ladder comprises a flange that can release the locking button thereby unlocking the stabilizer from its extended position and move it into the collapsed position.
