does its job and keeps the dirt out of my ratio rite. However i would have given 5 stars if the seal was a little bit tighter. currently it probably wouldn't hold oil in it if it tipped over. overall a great addition to an already great product.
This is just the lid.
The ratio rite has maximum measurement capacities in three columns of: 1 1/8 pints, 500 cc, 18 Fl. Oz.
The ratios are from 70:1 through 8:1 in four columns of 1, 1.5, 2, & 2.5 Gallons.
