The author of this article technically describes and justifies the type of telescopic tubular pillar he created, which consists of the only pillar in the world which has a double pin, as far as he knows. In order to carry out this justification, the author is forced to develop a technical mathematical theory for telescoping pillars and he takes advantage of this opportunity to discuss the system and the difficult mathematical calculations of a telescopic pillar, bearing in mind that the two pipes involved have different diameters and thicknesses, the infernal gaps and defective seating as well as the pillar support on the jobsite.
