Positive nozzle location through dowel pin ensures nozzle does not deflect or need re-adjustment when put back on a machine; Better cup wheel nozzle location directly in front of the end wheels; Stiffer nozzle setup which resists deflection at 100 psi pressure. Loc-Line typically deflects at 20 psi; What’s more, we’ve assembled this combination in one convenient kit for 2-spindle WALTER machines. Other
