Overview2-5

Coaxial cable connections to the housing are made using conventional 5/8 inch x 24 threads per-inch stinger-type connectors. Seven port plugs in the cover enable access to internal test points without opening the housing.

Two messenger clamps are attached to the side of the housing (Figures 2-5, 2-7) and are secured with 5/16 inch x 24 threads-per-inch stainless-steel bolts for strand (aerial) mounting. The bottom of the housing also contains two 5/16 inch x 24 threaded holes located on the horizontal center-line separated by eleven inches center-to-center (Figure 2-7). Use these holes and the bolts from the messenger clamps for pedestal and surface-mounting installations.
