Step 2 Mark the positions of L-shaped guide rails and floating nuts.
l An AR2240 router is 2 U high, which is the distance between six mounting holes. Mark
the mounting holes for L-shaped guide rails and floating nuts with a marker.
l An AR3260 router is 3 U high, which is the distance between nine mounting holes. Mark
the mounting holes for L-shaped guide rails and floating nuts with a marker.

Step 3 Install the floating nuts and L-shaped guide rails.
NOTE
The methods for installing floating nuts and L-shaped guide rails for the AR2240 and AR3260 routers
are the same, except that the installation positions of the floating nuts and L-shaped guide rails differ. An
AR2240 router is used as an example here to describe the installation procedure.
1. Use a flat-head screwdriver to install four floating nuts in the marked positions on the
front mounting rails, two on left and two on right. Ensure that the floating nuts on the left
and right are on the same horizontal plane.
