APPLICATION
Hazardous Location Window Kits are designed to be used on
Increased Safety (Ex e) enclosures in ATEX or IECEx Zone 1 or
2 hazardous areas. These window kits are made with a robust
heavy-gauge Type 316 stainless steel frame and a silicone gasket
to ensure a dust-, oil-, and water-tight seal. Designed for use
as viewing windows, these window kits are ideal for visibility of
internal enclosure components. The windows are easily installed
by making a cutout in the enclosure and attaching the window and
frame with included mounting hardware.
