Clever system, what you are visiting - Alurohrstücken not burred - stapled together in China ??? To enlarge the dry surface (eg. To 100 cm or more) get you to be 2 aluminum broomsticks at a price of about 2.50, both saw to the desired length, and already is the dryer "optimized" in hardware stores there are also aluminum tubes with the same diameter as the supplied "mini tubes" of Wenko, with a length of 2 m - price about 12 at Bauhaus or 25 at Max Bahr. All right ....?
