Abstract
A ratchet type telescopic load binder (1) having axially and oppositely moveable first and second threaded screw members (7,8) of different diameters is disclosed. The larger diameter member (7) includes an axial cylindrical void (11) into which the smaller screw member (8) is permitted to move. Greater reach is achieved by providing the smaller member (8) with a screw thread (10) pitch and a thread (10) length which are greater than those of the larger member (7). The cylindrical void (11) of the larger member (7) extends past its operative thread (9) length to accommodate increased penetration of the smaller member (8).
