A splayed or wedge coping is one that slopes in a single direction; a saddle coping slopes to either side of a central high point.

A wire gate, western United States. A Hampshire gate, New Zealand gate or wire gate is a type of agricultural gate formed from a section of wire fence which can be removed temporarily. This type of gate is used where access is only needed occasionally, or when the cost of a conventional rigid gate cannot be justified.
Coping is only ever used for internal corners. External corners are always mitred. The main reason that scribed joints are used is that timber shrinks in width far more than it does in length. By using a scribed joint rather than an internal mitre joint, the effect of shrinkage is minimised. Also it is possible to arrange the scribed joints ...
An example of the costs of fencing with lumber immediately prior to the invention of barbed wire can be found with the first farmers in the Fresno, California, area, who spent nearly $4,000 (equivalent to $102,000 in 2023) to have wood for fencing delivered and erected to protect 2,500 acres (1,000 ha) of wheat crop from free-ranging livestock ...

Tainter gates are usually controlled from above with a chain/gearbox/electric motor assembly. A critical factor in Tainter gate design is the amount of stress transferred from the skinplate through the radial arms and to the trunnion, with calculations pertaining to the resulting friction encountered when raising or lowering the gate. Some ...
