The rugged and reliable 1 gal (3.8 l) Eagle Type I Steel Safety Can. The pour or fill hole has an inner diameter of 1.65 in (4.19 cm) and the attached funnel helps to prevent spills and splashes when pouring into smaller tanks. And because this can measures 8 in (20.5 cm) high with an outer diameter of 9 in (22.9 cm), it's easy to store in your Eagle safety cabinet.
