Rack-mount brackets for 19-inch enclosures

The Vertiv RMKIT18-32 is a telescoping rail kit designed to mount compatible Liebert UPS units and battery cabinets into standard 19-inch rack enclosures. It supports rack depths from 18 to 32 inches. The kit includes two brackets, M5 and M4 screws, M4 nuts and a grease packet for installation.

Sustained load capacity of 198.42 pounds

Each bracket set is rated to hold up to 198.42 lb, allowing it to support heavy UPS hardware continuously without deformation. The steel construction and included hardware distribute weight evenly across the rack frame. This capacity covers the GXT 2U and 5kVA units plus associated battery cabinets during long-term deployment.

Fixed 19-inch rack standard limits flexibility

The brackets only fit 19-inch wide rack frames, so they cannot be used with wider or proprietary enclosure widths. Depth adjustability stops at 32 inches, excluding deeper cabinets from compatibility. Installers must verify their rack depth falls within the 18-to-32-inch range before purchase.

Questions about this item

Does the 198.42 lb load capacity of the RMKIT18-32 brackets require additional rack reinforcement for all-day operation?

The brackets support up to 198.42 lb. Reinforcement depends on the rack frame rating, not the bracket kit itself.

Which specific screws and nuts from the included M5 and M4 hardware must I already have tools for?

The kit includes 2 x M5 screws, 8 x M4 screws and 8 x M4 nuts. Standard hex or Phillips drivers for M4 and M5 fasteners are required.

Will the telescoping 18-32 inch rails align with the mounting holes on my older Liebert GXT 2U UPS?

The kit is compatible with Liebert GXT 2U, GXT 5kVA and associated battery cabinets. The adjustable rails span 18 to 32 inches to match rack depth.
