This drinker bottle includes a specially designed 2 litre bottle which gradually trickles water down into the trough.
The drinker is made from plastic with a long lasting stainless steel trough. To set this drinker up, the green plastic base should be twisted to fit into weldmesh with 1" x 2" or 1" x 3" holes. It can also be fitted to weldmesh with 1" x 1" holes, but you will need to make a cut into the wire.
Alternatively you can secure them with a spring.
