Round Adjustable-Length Shipping Tubes
Adjust these tubes by twisting the two halves. A hexagonal end prevents rolling. Use them to protect long, thin objects during shipping.
Twist-to-lock tubes can be slid up or down to adjust their length, so you don’t have to repeatedly twist the two pieces. To slide, turn the top tube into the sliding channel. To lock, turn the tube with the ridges into the grooved channel.
