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
