Behringer 921A Oscillator Driver Quick Start Manual page 2

Installation
The necessary screws are included with the module for mounting
in a Eurorack case. Connect the power cable before mounting.
Depending on the rack case, there may be a series of fixed holes
spaced 2 HP apart along the length of the case, or a track that
allows individual threaded plates to slide along the length
of the case. The free-moving threaded plates allow precise
positioning of the module, but each plate should be positioned in
the approximate relation to the mounting holes in your module
before attaching the screws.
Hold the module against the Eurorack rails so that each of the
mounting holes are aligned with a threaded rail or threaded
plate. Attach the screws part way to start, which will allow
small adjustments to the positioning while you get them all
aligned. After the final position has been established, tighten the
screws down.
