2 in 1 / telescopic
Two-piece spirally wound tubes in various diameters. The lower part with a smaller diameter is closed by a lid in a larger diameter.
As a rule, the two-piece telescopes are made entirely of cardboard; both the lower part and the lid can include a rolled edge and is finished with either a printed or blank disc on the top and bottom.
A special form of the two-piece telescope is telescope packaging in which one section is shoved into the other until the desired length or distance is reached. Through a precise and finely tuned wall thickness of the tubes, we can determine the fit between the sections and control the degree of suction as precisely as your application requires.
