3.2.1 Assembling the Shelf
Step 1 Attach the front bracket and shelf support to the left front rack post, as shown in Figure 5 . An
up arrow is printed on the shelf support to indicate its proper orientation.
Unthreaded rack holes: Use the M6 screws and cage nuts supplied in the accessory kit.
Threaded rack holes: Attach the front bracket to the post with screws that can be threaded
through the rack post. Secure the shelf support to the post with nuts that fit the screws threaded
through the post.
Step 2 Repeat step 1 on the right front rack post, assembling the parts at the same vertical level as those
on the left rack post.
Step 3 Attach the shelf support and back bracket to the left rear post ( Figure 6-left ). The shelf support
must be assembled at the same vertical level on the front and rear posts ( Figure 6-right ). An up
arrow is printed on the shelf support to indicate its proper orientation.
Unthreaded rack holes: Attach the parts as displayed in Figure 6-left .
Threaded rack holes: Attach the shelf support to the post with screws that thread into the rack
post. The back bracket is not required on threaded racks.
Step 4 Adjust the left shelf by sliding its components to fit between the front left and front rear rack
posts, as shown in Figure 7 .
