Frames completely made of plastic, non rusting, light, used for floor washing. The buttons on the upper part of the frame, if finger-pressed, close the tool at 180° thus preparing it for the squeezing of the mop head. The universal ring enables to use any handles with diameters ranging from 18 to 23 mm; the articulated joint makes the use of the tool easier also in hampered places. Available in the 40x11 cm version.
