Attaching the Rails to a Cabinet

Depending on the type of cabinetin which you will install the tray, use one of the following procedures to attach the rails:

“Attaching the Universal Rail Kit to a Standard Sun or 19-Inch Cabinet With Threaded Cabinet Rails” on page 27

“Attaching the Universal Rail Kit to a Standard 19-Inch Cabinet With Unthreaded Cabinet Rails” on page 31

Each tray requires two standard mounting rack units (2RU) of vertical space in the cabinet. Each standard mounting rack unit (RU) has three mounting holes in the left and right cabinet rails. The top mounting hole of the lower RU is always closest to the bottom mounting hole of the upper RU, hence the divsion between RUs on a cabinet rail is between the two closeest mounting holes in a grouping.

The universal rails have an adjustable depth of 24” to 34”.
