General Information                                                                   

The weld bead is minimal which allows another tube or another solid to slide inside the tube easily. Generally with standard rectangular tubes, a combination of the weld bead and the tolerance will not guarantee two tubes to slide inside each other easily. However, the telescoping tube has a minimal weld bead which allows the inside of the tube to be smoother and consistent throughout, thus allowing the tubes to be considered telescoping.
