The Metalclad modules are designed for use by manufacturers of line jacks with metal faceplates. The printed circuit board is identical to that found in the BT style 2 Series and 3 Series.

The plastic housing provides shuttering and fixing points to allow the module to be fixed to the metal faceplate.
 

The Metalclad modules are available in Master or Secondary versions and in three different colours (White, Black or Brown).
All variants use IDC terminals.
