Steel Window Kits are designed to be used on Type 4 and 12
enclosures. Stainless Steel Window Kits are suitable for Type 4,
4X, 12 and 13 enclosures in indoor or outdoor applications where
corrosion is a problem. These kits are easily installed by making
a cutout in the enclosure and attaching the window and frame in
place. Frames are made from heavy-gauge steel with an ANSI
61 gray polyester powder finish over pretreated surfaces or from
heavy-gauge Type 304 stainless steel with a brushed finish. The
window is .25-in. (6-mm) acrylic for steel kits or .25-in. (6-mm)
polycarbonate material for stainless steel kits. Oil-resistant
gasketing ensures a water-tight seal around the perimeter of the
window and frame. All mounting hardware is furnished. Custom
sizes, materials and finishes can be provided on special order.
Consult factory for information.
