Round Tubing Telescoping Compatible

For those looking for telescopic aluminum tubing, you've found the right place. Whether you're just looking to buy tubing, or want tubing, telescopic clamp mechanisms, end caps and more, Testrite Aluminum has what you're looking for. We sell cut to size round aluminum tubing from 3/8" Outside Diameter up to 1-1/2" Outside Diameter in 1/8" increments that telescopes.

All of our tubes in this section feature tight tolerances on both the wall thickness and ovality. Our drawn aluminum tubes nest one inside the other to enable snag free telescoping. These are often paired with our locking mechanisms, sold separately. These tubes can be used for other non-telescoping applications as well.

Are you looking for someone to do custom fabrication for you and need qty 25? In that case head over to and let us know how we can be of help.
