Adjustable Mailing Tubes

Measure the item after adding surface protection, end guards or bundling. Select a diameter that supports practical loading along the full product length. A tube that is too tight can abrade or bind the contents, while excess diameter can allow movement and increase the completed package size.

Select an adjustment range that covers the finished pack without using the extreme end of travel as a substitute for proper overlap. For shorter variable-length applications, compare premium telescoping mailing tubes. The joint design and range should suit the actual product length.

Set the tube to length while keeping all sections aligned and sufficiently overlapped. Secure the joint around its circumference and close both ends so the contents cannot push against or release the closures. Very long packages create leverage during lifting and conveyor handling, so inspect for bowing and unsupported spans.

The wall description does not provide a universal capacity for every length. Product weight, span, center of gravity, moisture and repeated impacts can change performance. Measure the completed outside dimensions and weight, then verify carrier maximums, surcharges and special-handling rules before using the package routinely.
