B-LINE FLWK133 – Frequently Asked Questions
1) What enclosure types is the Eaton B-Line FLWK133 window kit meant for?
The FLWK133 fixed frameless window kit is intended for Type 1 and Type 12 enclosures. Type 1 is general purpose indoor; Type 12 adds protection against dust and dripping non-corrosive liquids in industrial spaces. If you are working with a washdown or outdoor rated enclosure, this is not the kit for that opening.
2) What size cutout does the B-Line FLWK133 window kit cover?
The FLWK133 measures 14 x 14 x 4 inches as published, so size your enclosure door opening against those figures before you cut. It is a fixed frameless kit, meaning the polycarbonate lens mounts flush over the cutout rather than in a hinged frame.
3) Is the B-Line FLWK133 window kit UL Listed?
Yes, the FLWK133 window kit carries a UL Listing. For a plant or institutional MRO buyer standardizing viewing windows across control enclosures, that is the line item the inspector looks for on a Type 1 or Type 12 panel.
4) Is the window on this Eaton B-Line kit glass or plastic?
Polycarbonate. That is the impact resistant choice for an industrial panel door where a glass lite could be struck by a cart or a tool. It also keeps the assembly light, about .16 lb.
5) Does a fixed frameless window kit open, or do I need a hinged door kit?
Fixed means fixed. The FLWK133 gives you a sealed viewing lens over the enclosure cutout with no hinge and no access. If electricians need to reach meters, breakers or a disconnect through the opening without swinging the main enclosure door, you want a hinged window door kit instead, not this one.
6) What is the exact Eaton part number for this polycarbonate window kit?
Order it as Eaton B-Line FLWK133. That single model covers the polycarbonate fixed frameless window kit for Type 1 and Type 12 enclosures, so there is no finish or size option to specify alongside it.
