Use these hose trolley for a 25-m-hose 3/4 ", diameter 19 mm. With water stop Hose pieces of hose tree rolling up the heavy hose is always filled. I come as a right-handed with the rechtenFuß on the bottom tube and can stimulate. When stripping in exactly a straight line remains the cars are almost up to the last meter hose, otherwise it tilted and tipped. I like the metal carts.
