2.
mounting screw.
Partially insert a mounting screw into the top hole in each flange of the large shelf.

Tighten all the screws completely.

The router is shipped with each spacer bar attached to the rear of each front-mounting
5.
flange. Remove each spacer bar by removing the seven screws that fasten the spacer
bar to the front-mounting flange.
Place one of the spacer bars over an flange of the installed large shelf. Position the
6.
notch in the rear of the spacer bar so the upper part of the bar is flush with the rack
rail and the lower part is flush with the flange of the shelf.
Insert a mounting screw into each of the nonthreaded holes in the recesses of the
7.
spacer bar to secure the spacer bar.
Repeat Steps 6 and 7 for the other spacer bar.
