Adjust the Rear RETMA Rails

Language:

Note - You can move the rear rails in 25 mm (approx. 1 in.) intervals all the way to the rear of the rack.

Open both rack doors.
You might prefer to remove the doors from the rack before adjusting the RETMA rails. For instructions, see Servicing Doors.

Using a T-30 Torx wrench key, remove and save the 14 M6 screws securing the right rail to the rack frame.

Note - Do not discard these M6 self-tapping screws.

For the original racks, there are four sets of screws securing the rail to the frame and the support braces:

4 screws at the top the rail
3 screws securing the rail to the horizontal brace
3 screws securing the rail to the triangular brace
4 screws at the bottom of the rail

Note - To prevent stripping the screw threads, carefully remove these screws from the rack.

Caution - By separating the rails from the support braces in the older racks, you decrease the overall stability and strength of the rack. You can still use the horizontal brace if you move the front rails the same distance into the rack as you moved the rear rails (35 mm).

Note - The new racks have telescopic horizontal braces that can increase overall stability and strength of the rack, without having to move the front rails the same distance into the rack as you moved the rear rails.

Move the rail to the desired location and use a T-30 Torx wrench key to secure the rail to the rack frame and braces.
Secure the rail using four screws at both the top and bottom of the rail. Save the remaining six M6 self-tapping screws for future use.

For new racks with middle and bottom telescopic support braces, extend and secure the braces to the rails.
Secure the telescopic braces using five screws at both the middle and bottom rails.

Repeat Step 2 through Step 4 for the left rail.
