Type 4R has 2 vertical & 2 horizontal rollers with one rope-passing opening. The nominal sizes, of universal fairleads are denoted by reference to the outside diameter of the main roller in millimeter, in terms of the nearest number drawn from a basic series of preferred number. For the universal fairleads having the same roller diameter, the alphabetical character is followed by nominal size for the different SWL The nominal sizes are: 140, 160, 180, 200, 250, 300A, 300B, 400A, 400B and 400C.
