8U Rack Rails Kit for 19 Inch Racks

This StarTech.com MB240037 kit provides two 8U rack rails manufactured from cold-rolled steel with a black powder-coated finish. The package includes 40 M6 x 20mm rack mount screws, 40 M6 cage nuts, and 20 self-tapping installation screws. It is designed for mounting servers, network switches, and professional audio equipment into standard 19 inch racks or cabinets.

Installers Needing Complete 8U Mounting Hardware

The kit suits IT professionals, home lab builders, and audio engineers who require a ready-to-use hardware set for 8U of rack space in a 42U cabinet. It is not for buyers who need rails for a different rack unit height, metric threads other than M6, or tool-less mounting mechanisms. The included self-tapping screws also support direct mounting into unthreaded rack uprights.

Rack Unit Height Fixed at 8U

Each rail spans 8U of vertical space, measuring 14 inches in height, .7 inches in depth, and 1 inch in width with a total kit weight of 350 grams. This specific 8U dimension determines whether the rails match the equipment height you intend to mount. Confirm your device occupies exactly 8U before purchase.

Questions about this item

Is the 8U rail height right for my 42U rack?

Each rail spans eight rack units, so it occupies 8U of the 42U vertical space and leaves the remaining units free for other gear.

What does the 14-inch depth mean once the rails are mounted?

The rails are 14 inches deep front to back, giving that much support depth for servers or switches installed in a 19-inch cabinet.

How do the M6 screws and cage nuts work with a 19-inch rack?

The kit includes 40 M6 x 20 mm screws and 40 M6 cage nuts that thread into standard 19-inch square-hole uprights for a secure mount.
