I need a tent pole for it, but i don't know what model of Northface tent this is. It's an older model. couldn't find any tags other than a warning that it is flammable. image search brought up a similar older tent called the talus. The following pictures are of the tent without the fly...
Replacement poles also need to (or at least should) match the diameter and amount of flex from the original pole. From this perspective, off the shelf replacement poles that match the length won't always work. With a smaller tent, you could probably bring it into the store (on a slow day) and trial a replacement pole.
Did you know that 83.6% of all statistics are made up on the spot?
Good point about the pole because in this case just getting another 9mm pole may not work all that well. The original front pole was a DAC reverse combi , designed to have a wider radius in the middle . Looking at the photos I can't tell the difference (that is it appears to me that a standard 9mm pole would do that shape) but maybe not. I don't know of anyone that sells those poles.
But before trying to get that pole I suggest examining the fly very carefully because some batches delaminated, cracked or became sticky after a few years.
