Case for carrying three 15 inch hydrometers. Made of
plastic with separate compartments, each compartment
lined with felt. The lid has a 30° angle cut, which allows it
to arc away from the hydrometers when open, thus
preventing stem breakage. There are two models to
choose from. This model has a spring
loaded hinge that holds the lid open or closed under
spring tension. Dimensions: 16.5"L x 4.75"W x 2"H.
