Save on shipping costs by buying in bulk! When accidents happen, replace the udometer (glass vial) in your broken rain gauge with a 3-pack of these Toland Replacement Udometers. Everyone loves classic Solar Rain Gauges, Garden Delight Rain Gauges and Cattail Rain Gauges from Toland Home Garden, but accidents happen and when Fido gets out at night and bumps over your rain gauge you may need to replace the glass rain collection tube (also know as an udometer). These come in either clear or amber colored. Both colors fit all styles of rain gauges, so choose your favorite!
