About this file

These are technical drawings and specifications from the United States Department of the Interior, Bureau of Land Management (BLM), Idaho State Office, for let-down fence construction. The drawings, designated ID-078-02824-10 and dated January 2004 (revised August 2007), provide detailed illustrations of typical let-down fence designs and components used for wildlife management and range control on federal lands.

The specifications detail four primary fence brace types: tie tree brace, rock jack brace, and double H-brace configurations. Key components include metal T-posts, wooden cedar stays, 12-gauge galvanized wire, let-down fence clips, duplex nails, carriage bolts, hex nuts, and 12-gauge brace clamps. The drawings illustrate specific construction methods, including wire spacing (10-inch intervals), post heights (ranging from 30 inches to 3 feet-9 inches), and brace rail assemblies. The let-down fence design incorporates metal bailer clips that allow the fence wire to be temporarily lowered for wildlife passage while remaining securely fastened with duplex nails. The drawings include detailed cross-sections showing wire configurations, brace clamp details, and assembly specifications for corner installations. These technical standards would apply to BLM contracting for fence construction, repair, or maintenance work on public lands in Idaho.
