The troughs come with two plastic threaded fittings that allows easy attachment to a gate or fence. They serve two purposes, they secure a trough in place and make the seal watertight. The trough is versatile as it is suitable for feeding corn, milk or water. The plastic material makes it easy to clean, light weight and durable. The extra depth of the trough is useful for holding ample amounts of feed or liquid, and limiting spillage. In stock today, Call us now on 01229 820877 for delivery Or Collection.
