Mounting the MLS on a VersaTools rack shelf

Only products in the VersaTools line can be mounted to a
VersaTools shelf. Most 1U rack-mountable Extron
products can be mounted on the standard shelf.

Tabletop use

Each MLS switcher comes with rubber feet. For tabletop use,
attach a self-adhesive rubber foot to each corner of the bottom of
the unit.

Rack mounting

For optional rack mounting, do not install the rubber feet.
Mount the MLS on a VersaTools™ 19" 1U Rack Shelf (Extron
part #60-190-20) or a standard Universal 1U Rack Shelf (Extron
part #60-190-01). On the standard rack shelf, the MLS mounts in
one of four locations to the rear of the rack or in one of four
locations to the front of the rack.

1. If rubber feet were previously installed on the bottom of
the MLS, remove them.

2. Mount the MLS on the rack shelf, using two 4-40 x 1/8
screws in opposite (diagonal) corners to secure the MLS
switcher to the shelf.
