Bracket Arms

All brackets have identical 4" x 7" base plates (see illustration below) which mount on the pole by means of two 5/8" bolts. Slotted holes permit 4" to 5" bolt spacing. Parts are standardized wherever possible for flexibility of use with CBA-235, CBA-231, CBA-221, and CBA-331 bracket adapters which attach to the brackets and support fuse cut-outs, lightning arresters, potheads, and other desired assemblies.

Bracket Arms

Columbia bracket arms provide the styles, sizes, and strengths to design economical and safe configurations for distribution line circuits on tangent, angle, and corner poles.  A single-phase tap may be dead-ended on each of the four bracket arms illustrated.
