B-LINE FLWK52 – Frequently Asked Questions
1) Will the B-Line FLWK52 window kit work on a NEMA Type 12 enclosure?
Yes. The Eaton B-Line FLWK52 frameless window kit is intended for Type 1 and Type 12 enclosures. Type 12 is the dust-tight, drip-tight indoor industrial rating, so the kit is built to preserve that seal when it is cut into the door. It is not offered for washdown or outdoor Type 4/4X enclosures.
2) What size cutout does the B-Line FLWK52 window kit cover?
The FLWK52 kit measures 6 by 6 by 3 inches as published, so size your enclosure door opening against those figures before you punch or nibble the cutout. The window itself is fixed, meaning there is no hinged or latched door over it, so all access still happens by opening the enclosure.
3) Is the FLWK52 window polycarbonate or glass?
Polycarbonate. That matters in a plant or mechanical room where an enclosure door can take a knock from a cart or a tool, since polycarbonate will not shatter the way glass does. The whole kit weighs about .08 lb, so it adds essentially nothing to the door.
4) What is the difference between a frameless window kit and a framed or hinged window door kit?
A frameless kit like the FLWK52 mounts the polycarbonate lens directly to the enclosure door with no surrounding trim frame, which keeps the profile flat and the parts count low. A hinged window door kit instead gives you a swinging window you can open for access to a disconnect handle or reset button. The FLWK52 is a fixed window, so it is for reading meters, lamps, and HMI displays without opening the enclosure, not for reaching anything.
5) What part number do I order for this B-Line window kit?
Order Eaton B-Line model FLWK52. It is a single configuration, so there is no finish, size, or handing choice to specify with it.
