This is a simple two-piece mount for First Alert's little "EZ Fire Spray” aerosol can fire extinguishers. It mounts to surfaces using 3M's medium command strips (e.g. B0751S46TS on Amazon) and holds the can in a horizontal orientation.

The intent is that mounting these up on a wall or similar makes them more obvious in an emergency than being stuck in a cupboard or down on a counter. For those with little kids, having them up on a wall should make them less accessible to mischief makers while keeping them handy.

My understanding is that these are also known as “Tundra”. These appear to be discontinued, and this might just be a branding thing.

These should hold both the 18oz. cans currently available from Amazon, Home Depot, Lowes, etc. as well as the 14oz. cans we got in a two-pack from Costco several years ago; both versions appear to use the same can with identical physical dimensions.

For an adaptation of the bracket for vertical mounting see here.

Model Notes

This comes in two parts to make it quicker, cheaper and easier to print, at the cost of a little extra hassle in sticking the brackets to a surface.

I'd suggest that you stick to PLA. While it's more than possible to print this in other materials , PLA's stiffness means the bracket can be thinner, without worrying about it sagging too much under the weight of the can. Personally, I tried PETG, and found it to be far too flexible. Those with more exotic filaments should feel free to try and report back.

When dealing with the can's weight, here's a little play in both clips, especially at the top. I didn't want to go too aggressive as I only have a couple of examples of these for test fitting, and I found having a little play in the clips makes pulling the extinguisher out of the bracket easier than going super-tight and worrying about pulling the bracket off a wall, etc. You can probably scale the clips down a percent or two in the slicer if it's a concern - there should be plenty tolerance in the back surfaces for the command strips to allow for them to be a smidge smaller.

As such, this is probably the least suitable thing ever for mounting in something that moves. There isn't a lot of friction holding the can in place, and it's trivial to horizontally slide it out from both clips.

Mounting

Because this is printed in two parts, there's a risk of misalignment when mounting. The simplest procedure I could find to sort this out was along the lines of the following:

• Stick the command strips on both parts, leaving the wall side covering in place.
• Clip both parts around the can.
• Without removing the wall side covering from the command strips, press the can with its mounts against the surface you plan to mount it on. This will align the two parts so that both of the vertical command strip surfaces are aligned.
• Use a bit of masking tape to temporarily secure the brackets to the can in this orientation. That way, the brackets are less likely to shift around when you pull the backing tape off.
• Remove the backing tape from both strips, exposing their stickiness.
• Do the usual press and hold command strip dance to mount the brackets in the desired location.
• Remove the can from the bracket for 24h or so to allow the strips to adhere properly without having to hold up the weight of the can.

Why?

We've had a couple of these in the kitchen for a few years now, and thanks to a series of unfortunate events, I recently had to use one. While we have a larger traditional dry powder extinguisher nearby, this was closer at hand, and put the fire out in under a second.

It occurred to me that while I thought it was obvious where they were sat in the kitchen, others in my family didn't share that opinion. I cobbled this together to allow me to mount one in a much more obvious location (in this case, on the fridge). The other is in a horizontal mount on the wall on other side of the kitchen.

If you don't have some sort of fire extinguisher in the kitchen, then I can say from experience, you should get one. These aren't expensive - the replacement I got Home Depot was less than $15, and our prices are probably the highest in the US.

If you do already have these, I would strongly suggest that if you don't have the risk of little kids messing with them, you should take off the anti-tamper plastic seal ahead of time to make them quicker to use. They come from the store with a clear plastic shrink wrap around the top of the can and the cap similar to a lot of foods and medicines. I'd done this years ago (writing on the can with a sharpie to show there was no seal) and it greatly reduced the time taken to start using it. Instead of faffing with a seal while the fire burned, I was able to just grab the can, pul off the clear plastic top and squirt it on the base of the fire.

Finally, if you do have an extinguisher, resist the temptation to put it next to the cooker. I always figured that the stove would be the most likely location of a fire, and in our case, I was right. If I'd left the extinguisher behind the cooker, then the fire would have prevented me reaching it to put the fire out.
