TRANSON Extendable Poster Storage Tubes 2-Pack 24"–40" Adjustable Blueprints & Artwork Protection, Waterproof Impact-Resistant

TRANSON 2-pack extendable poster storage tubes are waterproof, impact-resistant carrying cases that adjust from 24" to 40" to protect blueprints, artwork, maps and posters during storage or transit.

These poster tubes are designed for anyone who needs a flexible, durable container that keeps rolled media safe from moisture, dust and bent edges. Each tube extends by twisting to lock at the desired length, comes with tight-fitting end caps and a removable strap for shoulder or hand carry. Constructed from sturdy, impact-resistant plastic and sized with an approximately 3.4" outer diameter, the set balances protection, portability and simple labeling.

How does the extendable length work and why does it matter?

The tubes rotate to lengthen or shorten between about 24" and 40" so you can store a variety of roll sizes without buying multiple cases. The screw-lock action keeps the tube at the set length, preventing slips while carrying or stacking.

• Adjusts from approximately 24" to 40" for different roll lengths.
• Twist-to-lock mechanism secures the chosen size.
• Fits posters, blueprints, maps, art rolls and documents.

Will these tubes keep my prints dry and clean during travel?

Yes — the design prioritizes moisture and dust resistance using moisture-resistant materials and snug end caps to reduce exposure to the elements. The sealed ends and durable shell also help keep pests and dirt out while stored in workshops, studios or vehicles.

• Tight-fitting caps create a protective seal against moisture and debris.
• Moisture-resistant tube material prevents light water damage.
• Impact-resistant shell guards against accidental knocks and compression.

How easy are these tubes to carry and organize?

Each tube is lightweight and includes a strap for hands-free transport, plus a clear labeling area on the cap for quick identification. The removable caps and simple length adjustment make packing and unpacking fast, whether you’re moving between job sites or organizing studio storage.

• Included strap for shoulder or handheld carrying.
• Clear labeling area on the cap for contents or project names.
• Lightweight design reduces fatigue during transport.

What sizes and capacity should I expect from these tubes?

The set covers a wide size range: when closed the tubes start near 24" and extend up to about 40", with an outer diameter around 3.4" and inner diameter roughly 3.1". That makes them suitable for standard and larger rolled materials while keeping them compact enough for racks or car trunks.

• Storage length: adjustable from approximately 24" to 40".
• Outer diameter ~3.4", inner diameter ~3.1" for multiple roll diameters.
• Two tubes included for project separation or backup use.

Who is this for? Artists, architects, students, designers and hobbyists who need reliable, weather-resistant transport and storage for rolled work will find this TRANSON two-pack practical and budget-friendly. It’s also useful for teachers, photographers and anyone who ships or stores posters, maps or blueprints and wants a reusable, adjustable container that protects edges and surfaces without taking up much space.
