The Induro DWRCH-2 Dual Wrench is identical to the wrench which is supplied with select Induro tripods, and is offered here as a replacement for a lost or damaged wrench. It has 10mm and 13mm sides.
The smaller 10mm side of this wrench is for the spiked feet for select larger Induro tripods, and the larger 13mm size adjusts the nut which holds the tripod head screw in place.
