This led to disputes recognized because the range wars between open vary ranchers and farmers within the late 19th century. The ranchers in place, particularly in the Texas Panhandle, knew that their holdings couldn't help the grazing of additional cattle, so the only alternative was to dam the migrations with barb wire fencing.

Corner posts are 15 to 20 centimetres (6 to eight in) in diameter or bigger, and a minimal 2.5 metres (eight ft) in length might include handled wood or from durable on-site timber equivalent to osage orange, black locust, purple cedar, or pink mulberry, additionally railroad ties, phone, and power poles are salvaged for use as nook posts (poles and railroad ties have been typically treated with chemicals decided to be an environmental hazard and can't be reused in some jurisdictions). Bracing wire is usually smooth 9-gauge. Line posts are set to a depth of about 76 centimetres (30 in). Posts are 10 centimetres (4 in) in diameter driven at the least 1.2 metres (4 ft) and could also be anchored in a concrete base fifty one centimetres (20 in) sq. and one hundred ten centimetres (forty two in) deep.
