Dear Sir/Madam,
This is CHRIS FISCHER from US.
I need a telescoping tube assembly for a device I am testing. The hollow tubing and other parts need to meet the following conditions :

2. Light weight
3. fairly rigid, but may flex some under side forces
4. Economically priced
5. Operating Temp range 0F to 130F
6. Material may be plastic or other, including fiber reinforced materials. Metals will likely be too heavy
The nested length of the assembly should be approximately 360mm (when all tubes are retracted into the largest tube).
The telescoped assembly must be able to extend by 11 feet (3.35 meters) from its
