How is a BlackLite tube better than a cardboard tube?
BlackLite tubes are designed specifically to be telescope tubes, while cardboard tubes are used as concrete forms. The phenolic resin impregnated into the paper fiber almost triples the strength-to-weight ratio, while also making it moisture proof and easier to work with. When comparing the price of BlackLite tubes to cardboard tubes, remember the cost of the flocked material that is already incorporated into the BlackLite tube. Finally, the harder phenolic surface allows the exterior to be finished to a high quality.
