4085 Drink Cups (pkg of 5)

Drink Cups - 4085
5 drink cups - No Mounting Brackets (Each cup requires its own bracket - catalog number 4084 or 4087) Cups have a spring-loaded trigger stem for positive shut off of water. Water flows only when bird's beak is in the cup. No messy wet spots as with nipple drinkers. Design a system with 1 or 2 cups or up to 210 cups. Each drink cup can handle up to 40 birds. Drink cups require a source of water at a pressure below 5 lbs. psi. Use 4020 pressure reducing valve for small systems & 4008 valve for larger ones. These units require 5/16-inch accessories.
