Canoe wrote:Beyond a yardstick between width and tape choices, it can also show us why the six inch wide bi-filament yields the most successful on-playa results. Like it's tolerance to mis-alignment when applied (meaning you don't have to get it aligned perfect to get good strength) and we can expect the same for losing a little bit of square inches of holding due to a little bit of dust. It is interesting to note that a 75 mph wind delivers up to 28 lbs./sq.ft. for 450 lbs. of force on a 4'x4' panel, or 900 lbs. of force on a 4'x8' panel. This 6" wide bi-filament tape, even when mis-aligned by up to 3/4", still calculates as strong enough to take that entire load on a single length of joint, and in practice, that force on the panel will be shared among three joints. So with the decreased holding strength due to the factors noted above, we can reasonable expect that 6" wide tape to do the job. And reports from the playa support that.
To ball park it:
Which pretty much reflects what people report as what happened on-playa:
- the 6" wide bi-filament tape yields strengths exceeding the 75 mph wind maximum loads,
- the 4" wide shows numbers in the range of those loads, and
- the 3" wide tape is below those loads.
And that's with the 220 lbs. | 91 oz. bi-filament tape.
- 6" wide = almost always good (application dust & errors unknown)
- 4" wide = usually o.k.
- 3" wide = often not o.k.
Use weaker tapes and you've got poorer results.

I live in Vancouver, Canada. Getting Bi-directional filament tape here is either impossible OR ridiculously expensive. I don't know why. I have however found a Canadian source for 3" hurricane tape (no such thing as 6" HT). Furthermore, MEC stocks smaller rolls. I plan to buy a roll from MEC and do some testing. If it works out like I hope, I'm going to order as much of the 3" tape as I can.
In the meantime, any playa-tested feedback would be welcome.
ps If anyone knows of a local source (or an online source that ships to Canada) of Bi-filament, please let me know. I'll walk your dog and massage your feet for a month.
