XL Door

I have installed your XL door and it’s performing as expected.  My dog uses it all the time.  We are at the end of our second week of daytime temperatures being as high as -15 C, and as low as -33 C.  This week the warmest it got was -20 C.  We’ve had a lot of snow and strong winds (30 – 50 km/h with gusts up to 70 km/h), and a couple of days of the wind and snow blowing directly at the door.  There’s sometimes snow that falls off my dog as he comes through.  There’s no way to stop that, but that’s the only flaw there is.
