- STRUCTURE STRENGTH
 

If there was ever any doubt that our little shelter could handle anything you could "throw" at it.....take a look at the pictures below! TOUGH.........and VERSATILE.
   TOUGH...

Skip the tough stuff and take me straight to versatile!

  • Yes, you can drag it on asphalt and concrete.

Keep in mind all these claims of strength have to be accepted on the basis of reasonableness. If you are fighting a forest fire and the wind changes, DRAG THAT SHELTER AND ITS CONTENTS OUT OF DANGER IF YOU CAN DO SO SAFELY. If you drag it a mile and the floor does scuff through, at least you saved the contents.

If you have to move your UniFold fast, the structure makes it easy. This shelter is empty, so the floor is not sagging too much when you pick it up.

If the floor had lots of gear on it, you needn't remove it to move the shelter. Just drag it and the floor becomes a handy skid for the contents.
  • Yes you can fold the UniFold like a taco shell and it still works perfectly.

Here we folded the shelter inside when it was warm enough to flex aggressively on itself.

Then we tied it folded with shipping strapping.

Then we took it outside and left it overnight on one of the coldest days in the Toronto winter of 99/00.

It was -20° C that night, and -15° C the next morning when we cut it loose and set it up.

Here it is.The tunnel set up as quickly as usual.

There is one point to note though. You have to pull the shelter open 'out' from the convex side of the warped pancake. If you pull from the concave side it will not open up unless you overpower the warp.

We prefer and recommend the easy way.

One of the strongest locations to bear a load is at the fold of the vertical side walls. Here a fish scale is showing the 50lb limit being applied to the anchor loop of the side wall.

You can literally support 50lb per fold on the side walls.

Excellent for keeping heavy turnout gear organized.

The strongest panel is on the end wall center post. Here 50 lb are applied with little effect. You can rely on this post to support items as well. However, it is possible to overload it if combined with heavy snow on the roof. This post is the point where the snow load is borne.

Windtest - That's 72.1 MPH showing on the hand held wind-meter (anemometer).

If you hate it when your brand new car has a fender bender, you're gonna love it when your brand new UniFold takes a hit.

See next pic.

Just pop out any crushed folds and the shelter is back to being like new. The very minor structural deterioration is insignificant.

There have been cases where additional headroom comes in handy. Here's how to make it. Just push out one of the roof folds. (No you can't do this to a whole bunch of roof folds, we already tried. When you do it to more than one, they bounce back and won't stay pushed out.) Look carefully and you can see the creases made by the corner crush demonstration above. Bottom line, the picture below proves it, UniFold is the Saturn of Shelters.

Look as best you can.

There is no permanent deformation after a fold is 'reset'.

More of the same.

Here's the result of a tough kick in the side panel.

UniFold rolls with the punches!

...and VERSATILE!

Cross flow ventilation is available by slitting an inward fold at the shoulder of the roof. The upper portion of the inward fold can then toggle outward and the resulting 'dormer' window has a roof that will protect from rain getting in. To keep the structure strong, the dormer has to be supported by a strut as shown.

With the strut in place, there is NO weakening of the structure.

 
You can also cut a square vent in the flat panel of a fold. This is ideal for a heater inlet duct, or for routing plumbing, wiring, or drains.
