B-LINE ES-90RMA-U – Frequently Asked Questions

1) What comes in the Eaton B-Line ES-90RMA-U mounting angle kit?
The ES-90RMA-U kit ships with two full length 'U' shaped mounting angles plus the mounting hardware to install them. It is an accessory for free standing enclosures, not a standalone enclosure or a fan, so you are buying the internal mounting rail set and fasteners only.
2) Will the ES-90RMA-U U angles fit a 90 inch tall free standing enclosure?
Yes. The angles are sized at 90 inches, which is why the part is designated ES-90. They are full length rails intended to run the height of a 90 inch free standing enclosure. Shorter cabinets need the corresponding shorter angle kit.
3) Is the ES-90RMA-U angle kit suitable for a washdown or corrosive area enclosure?
It is rated to NEMA 4X, the enclosure rating for corrosion resistance and hosedown conditions, and the angles are zinc with a yellow zinc finish. The kit is also UL Listed. Keep in mind the rating of the finished installation is set by the enclosure itself; these angles are internal mounting members that carry the same 4X classification.
4) What is the difference between a U shaped mounting angle kit and a solid back panel for an enclosure?
U angles like the ES-90RMA-U give you two vertical rails to bolt gear or sub-panels to, leaving the cabinet interior open for wireway and airflow. A full back panel gives you a continuous mounting surface you can drill anywhere. Pick the angles when you are mounting DIN rail, sub-panels or rack gear at fixed positions and want the depth behind them free; pick a panel when device layout is dense or not yet fixed.
5) How much does the ES-90RMA-U kit weigh, and is it a one person install?
The kit weighs 30 lb total for the pair of angles and hardware. Individually the rails are light enough to handle alone, but at 90 inches long they are awkward to position inside a standing cabinet, so most electricians set them with a second person or lay the enclosure down.
6) Can I order just one U angle instead of the pair?
The ES-90RMA-U is sold as a kit of two full length angles with the hardware, so it is a pair per order. If you are outfitting several bays in a lineup, count one kit per enclosure section.
