The Little Giant All-Purpose Funnel is great to use throughout the maple sugaring process. Heavy-gauge, corrosion-proof polyethylene plastic is safe to use at the high temperature of boiling sap and will not corrode or rust. Designed for use in cold climates, these funnels hold up under tough environmental conditions. Ribbed construction allows air flow for easy pouring. Comes with a built-in hang tab for easy storage when not in use. Made in the USA.
