Gator Hooks/magnetics and spray foam??

[kingcobb]

Based off the fact I can find no one online actually talking about this, I am convinced they don't work, but going to ask anyway.

Has anyone ever used gator hooks on spray foam? I'm going with closed cell, and the adds are intriguing for a storage/organization option.

However, even if the magnets are able to secure to the metal through the foam, I am guessing they would just tear up the foam underneath, so if you ever moved them it would just leave damaged foam behind?

Just curious if anyone has tried this?

I know some have used a metal plate they attach to the wall, but at that point, your just making a permanent fixture anyway so you might as well use wood and just screw into it?

You're asking if the magnet is strong enough to stick through a layer of spray foam?

 

[kingcobb]

No more if it damages the spray foam.

Gator hooks themselves says that the magnets will attach through spray foam depending on thickness.

I was just curious if anyone had tried and if it damaged the foam.

I'd doubt it damages the foam, as I doubt the magnet force is strong enough to actually stick.

I assume:

Outer siding
Foam insulation
Magnet

How thick is the foam?

2 inches closed cell is what I am looking at doing on the sides. I'm intrigued by the idea of the magnets, and I messed with some at a vendor booth earlier this year, I certainly believe they can hold 50lbs, they held my 8 year old who is right at 50lbs....but I'm dubious how good a job they would do through the foam.

Like I said, was just curious.

They won't work through 2" of foam

Not sure where you found information that they would.

A magnet's force is dependent on the thickness of the steel it is stuck on. A magnet that holds 50 lbs when stuck to a heavy piece of steel isn't going to do the same stuck to 26 gauge steel, especially if there is foam in between.

I glanced at the specs, IIRC they are rated at 16 gauge

Distance from the surface has the biggest effect by far; as stated, it's doubtful any magnet could support itself at 2" away, even on solid steel. The thickness of the steel has a very small effect compared to distance.

You would not damage the foam because it won't stick.

You would need to mount a steel plate of some sort on top of the foam to get magnets to stick. Gator sells a steel panel for this, but of course you could use just about anything made of steel.

Doesn't matter the magnet, nothing is going through 2" of foam, plus it's only 26g steel

You can't change the way magnets work

here's a link to the product, I had no idea what it was. Interesting snap feature, still no idea what it does?

Had a neo magnet the size of a hockey puck. Kept it inside a plastic tool box with more foam than that all around. The whole box could be stuck to anything!! That thing could hurt you if you weren’t careful!

Well, there is always something bigger. But Home Depot doesnt stock'em

Big magnets in the 100+lbs pull force are very scary. Watch those digits, pancake them easy

I second that.
I have suffered finger injuries (minor but still injuries) from handling super magnets.

I was just going to say. IF these are strong enough to even hold itself up thru 2" of foam, be damn careful when you unpackage them or you're going have a high speed projectile happening.
