Turn your Capsule into a Protein Feeder in minutes. Feed a variety of taller animals from deer and livestock to goats and horses on a timed, programmable basis. The tray is elevated off the ground to prevent feed from souring and to reduce the risk of worms. It includes everything you need to add on to your existing Capsule. Both trays are compatible with the 500- and 1,000-lb.-capacity Capsules. Impact-resistant polyethylene.
