Adapts pin type and line posts to reliable horizontal construction.
Construction Features:
Specially designed for tie top insulators, This type clamp features a long steel stud for
mounting on a variety of different diameter insulators. Nuts are captive at both ends for
ease off installation. A single bolt clamping feature makes conductor installation possible
with a standard wrench or hot stick without removing parts. Only three clamp sizes are
required for conductor diameters from .25 to 1.5 inches. No parts need be removed for
assembly to insulators or clipping in conductor. All cast parts are high strength heat treated
356-T6 aluminum alloy. Steel parts are hot dip galvanized for maximum corrosion
resistance. This series is also available in all-aluminum clamp having a cast 356-T6 high
strength heat treated aluminum body, keeper, and clamp with aluminum alloy stud, nuts,
and lockwashers. To order all-aluminum clamp specify catalog number using suffix AA. For
correct clamp size to use with a given conductor, and neck sizes of pin and post type
insulators, refer to tables in the engineering Data Section of this catalog.
