Need Extra Long 6" Diameter Cardboard Postal Tubes?


It's very easy to create your ideal length 6" (150mm) diameter cardboard tubes with our incredibly strong 'Art Grade' postal tube extension kits.

We can only make and stock a certain number of lengths of extra long postal tubes: so our tube extension kits allow you to construct extra long 6" or 150mm diameter cardboard tubes in a huge range of lengths that we don't hold as stock items. So whether you need 2m long, 3m long, 4m long, 5m long, 6m long, or even longer...then extension kits could very well be the way to obtain the tube length that you need.

The couplers for our extension kits are all cut between 448mm - 500mm long (appx)

Each postal tube extension kit includes two of the relevant size end caps with spare caps or plugs available if necessary.
