B-LINE ES-72RMA-U – Frequently Asked Questions

1) What comes in the Eaton B-Line ES-72RMA-U mounting angle kit?
The kit is two full length 'U' shaped mounting angles plus the hardware to install them in a free standing enclosure. The angles are zinc with a yellow zinc finish. You get a pair, so if an enclosure needs four rails (front and rear pairs) you order two kits.
2) Will the ES-72RMA-U 'U' angles fit my 72 inch tall free standing enclosure?
Yes, these are full length angles sized for a 72 inch high free standing enclosure. Height on the kit is listed at 72 in, so match it to the enclosure's nominal frame height, not to the panel space you want. A shorter or taller cabinet needs the corresponding length angle instead.
3) Is this a complete enclosure or just the internal mounting hardware?
Just the mounting hardware. The ES-72RMA-U is an accessory kit of two 'U' angles with fasteners, intended to be installed in a free standing enclosure you already have or are ordering separately. It gives you the rails to bolt panels, subpanels, and DIN rail carriers to inside the cabinet.
4) Are these mounting angles suitable for a washdown or outdoor NEMA 4X enclosure?
Yes. The ES-72RMA-U angle kit is rated for NEMA 4X service and is UL Listed, and the zinc construction with a yellow zinc finish is what gives it the corrosion resistance for that duty. Because the angles mount inside the cabinet, the enclosure's own gasketing and door still determine the final rating of the assembly.
5) What is the Eaton B-Line part number for the 72 inch 'U' angle mounting kit?
Order it as ES-72RMA-U, Eaton B-Line series. That single model number covers the complete kit, both angles and the hardware, so there is no separate hardware pack to add.
6) How heavy is the ES-72RMA-U angle kit, and is it a one person install?
The kit weighs 25 lb, which is manageable for one person to carry, though a 72 inch angle is awkward to hold square inside a cabinet on your own. Two hands on the rail and one on the hardware is the practical way to set them.
7) What are the overall dimensions listed for this B-Line 'U' angle kit?
Listed dimensions are 72 in height, 66.5 in length/depth, and 25 in width. Use the 72 in figure as the angle length when matching it to the enclosure frame; the other two figures describe the packed kit envelope, which matters for getting it through a door or into an elevator on a jobsite.
