Telescopic Steel Tube
from web site
Telescopic steel tube is specially manufactured to tight tolerances to enable each piece of steel tubing to fit snugly inside the next size up or down. This telescopic tube is produced from grade steel which has excellent weldability and machining properties.
Telescopic poles are often used for making furniture, frames, enclosures, and display units or perhaps even a telescope! The poles are priced and supplied individually so please ensure you order a minimum of two different sizes if your piping project is required to be adjustable.
