Steel Window Kits have a heavy gauge cold rolled steel formed
frame (cleaned and treated for paint endurance and adhesion),
painted ANSI 61 gray. The clear window is made of .25-in. (6mm)
impact-resistant polycarbonate material. They are ideal for indoor
and outdoor Type 3R, 4 and 12 applications.
Stainless Steel Window kits have a formed heavy gauge Type
304 stainless steel frame with a brushed nish. The clear
window is made of .25-in. (6mm) impact-resistant polycarbonate
material. They are ideal for indoor and outdoor Type 3R, 4X and 12
applications.
Non-Metallic Window kits are made of a single piece special
polycarbonate blend, Makrolon, that has enhanced impact, UV,
water exposure, absorption, and saturation resistance. They are
ideal for indoor and outdoor Type 3R, 4, 4X and 12 applications.
They are also ideal for non-metallic enclosures where exterior
metallic materials are not allowed and can accommodate up to .25-
in. enclosure material thickness.
All Window kits are easy to install and require a simple rectangular
enclosure cutout. All required hardware is furnished, along with
assembly and cut- out instructions. The gasket material on all
windows is resistant to oils, cutting uids and many other liquids.
Window kits of the same size use the same interchangeable cutout.
Custom sizes for Steel and Stainless Steel Window Kits are
available along with different nishes and gasket materials. Consult
nVent HOFFMAN for details.
