FAQ

Can side panels be added to the R412-3824B?

Side panels and enclosure accessories are available separately from Middle Atlantic. The base unit is an open-frame configuration.

What does the 12/24-inch width adjustment mean?

The horizontal post spacing can be set to 12-inch or 24-inch width to accommodate different equipment form factors and installation requirements.

Is this rack compatible with standard 19-inch rack equipment?

Yes. At the standard EIA-310 19-inch equipment mounting width, equipment mounts normally. The 12/24-inch refers to overall post width, not the equipment mounting width.
