A duplex/tunnel section consists of two or more panels placed adjacent and connected to each other to form an enclosed relay and control tunnel system.

Typical Features Include:

• Carbon Steel, Stainless Steel, or Aluminum Construction

• Necessary framing, cross bracing, and stiffeners to form a rigid, planar, self-supporting structure

• Closely assembled vertical sides to minimize visible seam gap with panel front

• Matched panels, trim, doors and frames to present a neat appearance when assembled

• Flexible design to facilitate future duplex additions

• 3-way switching for lights provided at each entrance

• Design for concealed internal tunnel wiring

• Meticulous combined wash and phosphating prior to receiving a dual paint process

• Optional rack, cutout, auxiliary, or mosaic panel faces
