Hello all,
The distance between the front mounting bar and the inner side of the front door varies according to the cabinet type. Because the system enclosure is fixed on the front mounting bars, a longer distance between the front mounting bars and the inner side of the front door can result in less cabling space at the rear of the device. In such a case, you can install U-shaped brackets to move the system enclosure forward for more cabling space.
A U-shaped bracket is a mechanical part installed between the mounting ear of the enclosure and mounting bar of the cabinet to adjust the relative position between the enclosure and the cabinet. A maximum of two U-shaped brackets can be stacked.
U-shaped brackets are classified into three types: 25 mm, 50 mm, and 75 mm.
If U-shaped brackets are not installed, the system enclosure is fixed to the front mounting bars by using captive screws. The distance between the front panel of the system enclosure and the inner side of the front door is fixed.
Install the U-shaped brackets on the front mounting bars, and then secure the system enclosure to U-shaped brackets of the respective size. This allows you to adjust the distance between the front panel of the system enclosure and the inner side of the front door within a certain range.
Procedure of Installing U-shaped Brackets and Adjustable Guide Rails
1. On the front of the cabinet, align the bottom edge of the adjustable guide rail with the U scale on the front mounting bar, and fully insert the front positioning pin into the square hole.
2. Extend the adjustable guide rail and insert the rear positioning pins into the square holes on the rear mounting bar.
3. Align the U-shaped brackets with the adjustable guide rails, and then use M6 screws to secure the U-shaped brackets and the adjustable guide rails, as shown in Figure 5-22.

4. (Optional) Install floating nuts on the U-shaped brackets. For details, see (Optional) Installing Floating Nuts.
Floating nuts have been installed on U-shaped brackets before delivery. If no floating nuts have been installed, install a floating nut into the third hole on each U-shaped bracket.
Follow-up Procedure
· After the U-shaped brackets are fixed to the front mounting bar and the floating nuts are installed, install the storage device onto the U-shaped brackets, as shown in Figure 5-23, Figure 5-24, Figure 5-25, and Figure 5-26.

· U-shaped brackets can be stacked. When stacking the U-shaped brackets, comply with the following rules:
Stack two U-shaped brackets at most on each side.
Install the wide U-shaped bracket onto the adjustable guide rail and stack the other on it.
Install floating nuts in the first and fifth holes to connect two U-shaped brackets.
Figure 5-27 and Figure 5-28 show how to stack two U-shaped brackets.
