Rack Mount System 19"

I am working on building a relay testing rack mount system and needed to have some custom brackets made. In designing them and printing them I have saved a significant portion of custom manufacturing costs.

Hardware Required:
6-32 1/4" length machine screws, Digikey H154-ND
6-32 1/2" length machine screws, Digikey H360-ND
2" Hex Standoffs 6-32 female-female, Keystone Electronics 2214, Digikey 36-2214-ND
1/2" Hex Standoffs 2-36 female-male, Keystone Electronics 8414, Digikey 36-8414-ND

Assembly:

Printed Parts
2 Panel_Mount
2 Center_Mount
2 Rear_Brackets (Modified to suit your needs)
2 Front_Plates (Modified to suit your needs)
? Rear_Mount_Vert/Horz if you need to mount terminal blocks or wiring harness
? Back_Plates (Modified to suit your needs)

1. First take the two Center_Mount pieces, insert four 2" standoffs into one of them, then press the second Center_Mount onto the exposed 2" standoffs ends. Use 6-32 screws to pull the spacer into the properly seated position.

1.1 Remove all screws from the completed center mount assembly that were used to seat the spacers.

1. Take the two Rear_Brackets and attach them to the center mount assembly using the 6-32 1/2" machine screws.

2. Insert 2" standoffs into the outer ends of the Rear_Brackets, secure these spacers using 6-32 1/2" machine screws.

3. Attach the two Panel_Mount pieces to the spacers that were just installed in the previous step, do not install any machine screws.

4. Next take the two front plates that you have used/designed and attach them to the Panel_Mount and Center mount assembly using 6-32 1/2" machine screws.

5. If using my Rear_Brackets they must be tapped, perform this using a 6-32 tap, take care to clean the tap after the completion of each hole. At this time it would also be beneficial to tap the small holes in the Rear_Mount_Horz/Vert as well.

6. Install the 1/2" Standoffs to the Rear_Bracket tapped holes, the purpose of the standoffs is to allow additional room for wire/cable management.

7. Depending on if you are using horizontal or vertical back plates, install the appropriate Rear_Mount to the standoffs and secure using 6-32 1/4" machine screws.

8. Install the Back_Plates to the Rear_Mounts using 6-32 1/4" machine screws
