Tripod gravity feeders are intended for non-salt-based feeds—commonly whole corn and protein pellets. Avoid salt-based mineral supplements, as they may damage the feeder.
Most listings describe a roto-molded plastic barrel paired with galvanized metal hardware; some product details simply list the overall material as plastic or metal.
Common features include a 10-inch feeder port set at a 10° angle, drain holes and a 1-inch overhang to slow feeding and control spills, plus an adjustable 3-way inner sleeve to regulate feed flow.
Feed flow is typically adjusted with a 3-way inner sleeve or flow-control that you turn to open or restrict the outlet. Turning the sleeve increases or decreases the opening so you can accommodate different feed types.
Common features include drain holes to remove water, a roto-molded plastic barrel that helps reduce condensation buildup, and a 3-inch-deep hatch lid (also noted for tamper resistance).
