For Non-Jacketed Metal Clad Cable.
Type PK: Malleable Iron. Type PK-A: Aluminum.
O-Z/Gedney Type PK and PK-A connectors are used with any type of non-jacketed metal clad cable to terminate and ground the armor and secure the cable where it enters a cabinet (max. 1⁄4" thick), through a standard knockout, slip hole or drilled and tapped entrance.
Type PK and PK-A terminators accommodate a wide range of cable armor diameters in a given fitting by simply inserting fiber rings to provide armor stops for smaller diameters. An armor clamp with clamping pieces on each side allows the cable to be centered in the fitting and provides full contact with the armor to ensure a positive ground (3 ⁄4", 1" and 6" trade sizes have one clamping piece located on one side only).
