To secure the mid-bracket, follow these steps:
1 Align the mid-bracket (callout 2) with the four rail slots
See Figure 30 on page 62 for a flush mount assembly.
See Figure 31 on page 63 for a mid-mount assembly.
2 Insert and secure the four screws (callout 1) from the rack mount extension assembly, allowing some
play to adjust the mid-bracket position within the slot space when securing the assembly to the rack
post.
3 If the assembly will be used in a mid-mount configuration, insert a cage nut (callout 4 in
page 63) into the rail ear square opening (callout 3).
Two cage nuts are included with the SSA Universal Rack Mount kit.
