End assemblies
The most important part of a fence is the end assembly. Also called a strainer assembly, it literally holds the fence up. The two most common types of end assemblies are the diagonal stay assembly and the box end assembly. Each type uses a large strainer post set deep into the ground. The strainer takes the weight and strain of the wires. However, on its own the strainer post would eventually fail and tip over. It needs to be stayed correctly to support the rest of the fence.
A diagonal stay or brace end assembly is shown below. These end assemblies use one or more diagonal stays depending on their position in the fence.
The box end or horizontal stay end assembly uses an extra post and a horizontal stay. A wire windlass helps to distribute the load.
Strainer posts and stays are made of timber, steel or concrete. They are placed in corners, at gateways and at angles where the fence line changes direction. They should also be positioned at the tops of hills or ridges and at the bottom of gullies. Extra strainers should be included at intervals in long fences over flat ground.
