Square Telescopic Aluminum Tubing
At Testrite Aluminum, we specialize in precision-engineered square telescopic aluminum tubing designed for telescoping. Whether you need square aluminum tubes ½″ square, ⅝″ square, ¾″ square, ⅞″ square, or 1″ square aluminum tubing, we’ve got you covered—with consistent, telescoping friendly tolerances and lengths cut to your needs.
Our square telescopic aluminum tubing is specifically designed to slide inside one another (for example, the 0.5″ square aluminum tube fits neatly into the .625" square aluminum tube which slides into the 0.75" square aluminum tube, and then into the 0.875" square aluminum tube, which fits into the 1″ square aluminum tube) so you can build adjustable frames, display systems, supports, stands or extension mechanisms that telescope without rotation. Each size is engineered for compatibility with our full range of square tubing locks, snap-button inserts, and accessories to ensure secure, repeatable operation. Note tubing locks may need to be glued in place, watch the video below to learn more.
To provide enough clearance for telescoping, our tubes are in 1/8" increments resulting in clearance (room) between the tube sections. You can use our telescopic tubing locks to reduce play between sections significantly. Pair those locks with a spring button for any weight bearing applications. This Made in the USA square aluminum tubing is great for a range of applications.
