Cardboard Couplers for Extending the Length of Cardboard Tubes
Extend your cardboard tubes with our pre-slit couplers to produce extra long postal tubes for large posters, banners other artwork or industrial & engineering parts.
Simply use the couplers with whatever number of tube lengths you need to achieve the overall length required. Multiple couplers / extension collars can be utilised to join our tubes to achieve an almost limitless range of lengths.
Customers regularly utilise our couplers for postal tube lengths of 250cm, 300cm, 350cm, 400cm, 450cm, 500cm, 550cm or even longer 600cm & 700cm. But they can of course be used for much longer postal tubes on the occasions that extremely long tubes are needed.
Our 100mm diameter cardboard tube couplers are 448mm - 500mm long (appx).
