Abstract This disclosure relates to a wire strainer for straining or tensioning wire. An actuation arrangement is disclosed for use with a wire grab device may be 5 used in straining or tensioning fence wires for agricultural purposes. The actuation arrangement is attachable to the wire grab device. The actuation arrangement is movable along a chain including chain links to tension a wire fence. The actuation arrangement includes a lever that is movable between a first position and a second position to cause the actuation arrangement to move along the chain, a first pawl 10 and a second pawl that are spaced apart along the lever and pivotally mounted to the lever. As lever is moved between the first and second positions, the pawls alternately hook into the chain links to move the actuation arrangement along the chain. The actuation arrangement also includes a connector being pivotally mounted in relation to the lever at a location in between the pawls. The connector 15 is configured for attachment to the wire grab device. The actuation arrangement may also include at least one notch in the lever at a location such that the connector is able to move into the at least one notch when the lever moves into the first position or the second position. The connector pivot point may be offset from one or both of the first pivot point and the second pivot point, the offset being in a 20 second direction that is perpendicular to the lever longitudinal axis and laterally opposite to the general first direction of projection of the pawls.
