Shipping Tubes

Square Adjustable-Length Shipping Tubes

These tubes are easier to label and stack than round tubes. To adjust the length, push the ends of the tube together or pull them apart.

Round Adjustable-Length Shipping Tubes

Adjust these tubes by twisting the two halves. A hexagonal end prevents rolling.

Recycled Plastic Square
Adjustable-Length Shipping Tubes

Made of recycled polyethylene, these shipping tubes are a sustainable alternative to other plastic shipping tubes. They won’t roll around, making them easier to label and stack than round tubes.

Rectangular Adjustable-Length Shipping Tubes

Less likely to tip over or roll around during shipping compared to round and square tubes, these tubes are wider and flatter. Push the ends together or pull them apart to adjust the length.

Recycled Plastic Round
Adjustable-Length Shipping Tubes

Made of recycled polyethylene, these shipping tubes are more sustainable than standard plastic shipping tubes. Push the ends together or pull them apart to adjust the length.

Sealed-End Round Cut-to-Length Shipping Tubes

These tubes have one sealed end and one end that closes with a cap.

Round Cut-to-Length Shipping Tubes

Close these tubes with a cap on each end.

Square Cut-to-Length Shipping Tubes

Because of their square shape, these tubes can be stacked, and the flat surface is easier to label than a round surface.

Triangular Shipping Tubes

Easier to stack and label than round shipping tubes, these triangular tubes fit snugly next to one another without gaps and won’t roll because of their low center of gravity.

Square Shipping Tubes

Because of their square shape, these tubes won't roll away. They can be stacked, and the flat surface is easier to label than a round surface.

Square Shipping Tubes with Internal Holder

Secure drill bits and other long, sharp items firmly in place for storage or transit. The end caps on these shipping tubes have an internal holder that keeps your item centered between the walls of the tube.

Round Shipping Tubes with Slip-On End Caps

Slide the 6" long cap onto one end; the other end has a permanent steel cap.
