Alternative Means Of Attaching Straps/Support for Raceway To Storm Shelter

[Ravenvalor]

Hello,

I have a customer who would like for me to install a receptacle inside a metal storm shelter however the manufacturer does not allow for drilling holes through the walls of the shelter.
And the homeowner does want me to spot weld anything on the walls as well. Would someone please suggest an alternative method for supporting 3/4" PVC to a steel wall? I only need 2 - supports.

Here is a link to the shelter.

Extreme Above-Ground Tornado Shelter | Survive-a-Storm

The Extreme above ground tornado shelter from Survive-A-Storm comes in several sizes, for residential storm protection for 5-16 people.

Thank you,

For mounting to steel we use a stud welder. Seems like overkill for two straps. What about some type of epoxy?

He is actually researching epoxy but I never thought about a stud welder. Thanks.

Don't extend anything onto the walls. I have a metal underground storm shelter.
On a storm shelter, less is more in my opinion. It's not like you're going to live down there.

I used the 3/4" threaded entry into the back of a 2g wp box for a GFI and regular receptacle protected by the GFI right at the entry location.
I wouldn't have even done that if not for the need of a small electric heater, maybe a light or phone charger if needed.

Probably should have opted for (2) 3/4" threaded entries if you're thinking about a Cat 5 or phone cable in addition to the power since you cant mix them with both with only one entry.
In my opinion, The more you put in it as far as Cat 5's or phone lines,the more you're inviting trouble into the shelter.

The jack and 4x4 blocks I have in it are the most important things to have down there in case something happens to fall over the door, and, always call someone prior to going in or down.

Perhaps you could use a magnet like one of these:

Thanks for the good advice. I will let you know what they decide.

Very common to use magnets on water towers to hold coax runs.

One manufacturer is using magnets on commercial LED rack lighting reducing installation time, and are prewired. You see them dangling in the racks at Big Orange all the time! LOL!

Synchro shared knowledge of some magnets with us earlier. Would an inspector be ok with them?

Thanks for the advice.

Why do you have to extend the outlet beyond the entrance fitting?

Why are you having to run any conduit at all ?

I plan to mount a WP box directly on the 3/4” inlet on the inside of the structure. Then on outside run 3/4 rigid up wall and install an LB

I've worked with a few of these (Their HQ is just down the street from my son's school) and the idea is that you'll install a box on top of the threaded entry, not run anything across the walls. Most people leave a battery charger in there with a lantern.

Just spoke with the inspector and he said that epoxy would be ok for the outside straps.
Thanks for all the great help.

And here all this time I thought you were running the pipe on the "inside" of the unit.

That was actually my initial plan but the idea that you all put forth about just mounting the box directly on the inlet seems like a great idea.

Thanks for the help..
