This 8 Gallon capacity gravity feeder comes complete with 5 Peach Teat Nipples, 5 Teat Caps (Holders for the teats - as some can be replaced with "blanks" turning the feeder into a 3-4 station feeder), and all the hardware needed to hang this on a rail or fence. Constructed of durable, impact resistant polyethylene. UV protected for outdoor use and years of use. Rounded edges for easier cleaning ! No inside compartments - which reduces the bunting from faster drinking calves ! Call our warehouse at 800-680-3167 for pricing.
