Horizontal Drum Cast Iron Fill Gauge allows you to easily check liquid level of a horizontal drum at a glance - no more surprise re-orders or stock depletions. Use indoors or out, wherever you need to monitor the liquid level of drum contents. Sight gauge shows how much liquid remains in a 30- or 55-gallon drum.
Drum gauge installs easily by threading into a standard .75" NPT bung hole and accepts any .75" faucet.
