Enclosure Window Kits

Enclosure windows can be installed in electrical enclosures to provide safe visibility for viewing and monitoring equipment inside without opening the enclosure door. Hinged window kits can be installed on enclosure doors that already have switches, meters, lights or other components mounted on them. The hinged window kit is placed over the components and allows access to them with a hinged window that opens. Some window kits are specially designed for hazardous areas. The window kits are installed by making a cutout in the enclosure and attaching the window and frame with mounting hardware. They allow viewing inside an enclosure while ensuring that no water, oil or dust can enter.
Hoffman Window Kits are easy to install and require a rectangular enclosure cutout. All required hardware is included, along with cutout and assembly instruction. The gasket material is resistant to oils, cutting fluids and many other liquids.
Hoffman CONCEPT Fixed and Hinged Window Kits are designed with die-cast aluminum frames and clear polycarbonate windows. They are secured to the front opening of an enclosure. Hinged window kits are hinged on the left side and have a single-point slotted latch.
CONCEPT Deep-Hinged Window Kits provide visibility, protection and easy access to components and equipment installed behind the viewing area. They have a 2 inch space between the enclosure front opening and the window surface to accommodate switches, meters, lights and other components.
Hoffman Frameless Window Kits are designed for use with many Type 12 and 13 enclosures located indoors. The scratch-resistant polycarbonate window can be cut to smaller sizes and special high-strength, double-sided tape is supplied as well as screw fasteners.

Cutouts are very common when modifying enclosures for push buttons, indication lights, conduit entries or mounting hardware. Cutting into an enclosure runs the risk of eliminating the protective nature of the NEMA rated attributes. Proper steps must be followed in order to preserve the NEMA rating of an enclosure.
Devices mounted to the enclosure must have the same NEMA rating as the enclosure. This means that if the devices are installed to the manufacturer's specifications, they will be able to maintain the NEMA rating of the enclosure.
Water tight conduit hubs must be used when running wire through a cutout in an enclosure. There are many different types of conduit hubs that are used to secure conduit to an enclosure. However, only certain conduit hubs are rated for a watertight seal. By using water tight hubs, the NEMA rating of the enclosure is maintained.
Bonded washers are necessary when mounting hardware to an enclosure. If standard mounting hardware is used, the NEMA rating of the enclosure will no longer be maintained. Bonded washers have rubber gaskets that make a watertight seal around the drilled hole. It is also important to make sure the material used for the bonded washer matches the material of the enclosure. Stainless steel enclosures require stainless steel bonded washers.
