Question: I am currently working on a panel change with a 200 amp murray flush mount and I cant seem to fit uni-strut in ive tryed the smaller uni-strut to no avail is there any other way to properly secure the 2" main besides unistrut?
Alternative Mounting Methods for 2" Mains in Flush Mount Panels
1. L-Brackets with Strut Inserts
Cut L-shaped brackets from steel or aluminum. Drill or punch holes for strut inserts (nuts welded inside the strut). Bolt the L-brackets to the back of the panel and insert the strut into the inserts. Mount the 2" mains onto the strut.
2. S-Hooks or J-Hooks
Attach S-hooks or J-hooks to the back of the panel using bolts or screws. Hang the 2" mains from the S-hooks or J-hooks. Ensure the hooks are rated for the weight of the mains.
3. Mounting Ring
Install a mounting ring (similar to a raceway ring) around the 2" mains. Bolt the mounting ring to the back of the panel. Tighten the screws on the mounting ring to secure the mains.
4. Custom Mounting Brackets
Design and fabricate custom mounting brackets that are specific to your panel and mains. Weld, bolt, or otherwise secure the brackets to the panel. Mount the 2" mains onto the custom brackets.
5. Open-Slot Channel with Nut Inserts
Install open-slot channel (similar to strut) with nut inserts along the back of the panel. Bolt the 2" mains directly to the channel using the nut inserts.
Note: Always refer to the manufacturer's instructions and local building codes for specific mounting requirements. Ensure that all mounting methods provide adequate support and prevent excessive movement of the mains. Use appropriate hardware and torque values to secure all connections. Flag for review
