This is a technical specification drawing for standard cattleguard base details for use in the Black Hills National Forest. The document (Drawing 619-05, Page 02 of 02) provides detailed engineering specifications and assembly requirements for cattleguard base construction.

The drawing presents four detailed views of the cattleguard base assembly: a Detail of Steel Placement showing #4 rebar configuration with 3/4-inch diameter anchor bolts extending 2 inches above concrete; a Base End View Detail of End Plate depicting a 24-inch wide plate with 6 studs (3/4-inch diameter) welded and embedded in concrete, with 13/16-inch diameter holes spaced at 2.5-inch intervals; a Base End Locking Channel view illustrating a C10X15.3 channel measuring 8 feet 5 inches in length with 13/16-inch diameter holes; and a Base Side View, Base Top View, and Lift Eye Detail showing the overall 30-inch height, 8-foot locking channel dimension, lifting cutouts, and bolt placement specifications.
