Telescoping Aluminum Tube Ends & Attachments


Solid Aluminum Threaded Bushings

For rigorous applications.  Machined so tubes meet perfectly "flush" when screwed together. Made on our own automatic screw machines, all diameters are available. Custom threaded bushing inserts can be made for any commercially available thread.


Swaged aluminum tubing provides an economical way to form leg ends, so one leg nests into another. A swage and spring button can be an option. Swaging features close tolerances and provides great strength. We are tooled up for 3/4", 1", and 1-1/4" diameters. For other diameters - there is a one time, non-recurring setup charge. Available with and without optional steel Spring Button.

Spring Button Telescopic Tube Ends

Use Spring Button Ends to join telescopic tubes together and to attach accessories. Spring button ends are a cost efficient treatment for aluminum tube assemblies, enabling tool free attachment to other tubes or accessories. Available for all diameters.

Threaded Connectors

We can manufacture your custom telescopic aluminum tubing with male or female Threaded Connectors. Use one of each to join two tubes together.  Very cost effective. Available for all diameters. Available in 1/4 - 20 or 10-32 in many sizes.

Swivel Joints

All metal Ball and socket Swivel Joints allow for 360 degree rotation of two telescopic tubing assemblies. Made from metal castings and aluminum ball swivels, these pieces are durable and have some heft.
