Abstract: A telescoping device uses pins resting in grooves to serve as stop means for telescoping tubes. Each of a set of telescoping tubes has at least one groove running longitudinally along the outer tube circumference. A set of two right angled pins rests in a groove, the first pin extending outward through an aperture in the next largest tube's wall, the second pin extending inwardly through a groove aperture to serve as a stop for the next smallest tube. When the tubes are collapsed inwardly, the progress of each tube is stopped by the second pin in the next largest tube. When the tubes are extended outwardly, the progress of each tube is stopped by the abutting of the first and second pins' ends in a groove.
