Hey any of you guys or gals know where I can get a dispenser for 2.5 Gal Herbicide jugs? I would like a pump that fit the opening. But I would go for a cap with a spigot. I have found them for the 63mm 5 Gal Jerrie cans, but not the 2.5 Gal jugs. Does anyone know what the threaded opening size is on the 2.5 jugs? We do not use enough product to go with the 55 gal drum. But we do fill the backpacks and the low volume sprayer enough in a day that we are always dripping or spilling a little each time we load.
