A roller assembly including a frame including first and second arms spaced apart from each other, each first and second arm having an inner and outer side and a mounting projection located on the inner side of each arm, each mounting projection having a proximal portion adjacent the arm on which it is located and a distal portion located away from the arm, the distal portion having a smaller diameter than the proximal portion, a first elongate shaped plate having an aperture rotatably mounted to the inner side of the first arm, the proximal portion of the mounting projection on the first arm extending through the aperture rotatably mounted to the inner side of the second arm, the proximal portion of the mounting projection on the second arm extending through the aperture in the second plate, each plate being adapted for connection to opposing ends of two or more rollers so as to permit rotatable mounting of the rollers to the plates and to hold the two or more rollers substantially in a single plane, the plates and the rollers connected thereto being rotatable through 360 DEG , each plate being detachable from one of the first and second arms to permit a single roller to be mounted to the mounting projections of the first and second arms by locating the distal portion of each mounting projection in a passage in each opposing end of the single roller, and a handle connected to the frame for holding the assembly, the handle positioned at an angle to the plane or positionable at an angle to the plane.
