This document is a set of technical specification drawings for typical barbed wire fence construction issued by the United States Department of the Interior, Bureau of Land Management. The drawings provide detailed specifications for various fence components and configurations used by the federal government.

The document includes standard detail drawings for barbed wire fence (4-wire), woven wire gates, and mechanical gate closers. Key components illustrated are: end panels (Type I and II), stress panels, line panels with specifications for wire spacing and post materials, corner panels (three-post, four-post, and five-post configurations), mortise details for spike/toe nailing, and brace clamp details. The fence specifications indicate minimum dimensions including 6'-0" to 6'-6" post spacing, 6'-6" minimum brace spike height, and provisions for both wood and steel line posts. Wire specifications include 9-gauge smooth galvanized wire for gates and panels at minor depressions, with twisted wire or wood stays for reinforcement. The drawings note that all fittings and tie wire shall be galvanized, and specific requirements for post spacing, wire gauge, and stay configurations are detailed in accompanying specifications. Wire gate designs (Type A and Type B) are shown with smooth wire loops at openings and 4-2" x 2" wood staves evenly spaced. Mechanical gate closers are depicted with elevation and plan views showing gate post, closing device, and smooth wire loop configurations. The document was designed by others, reviewed by J. Laws, and approved by V. Whitten, with a drawing date of April 26, 1997, and subsequent format updates dated July 31, 2009.
