What material are those made from?

The holes are quite big.

PA 6.6 nylon same as normal zipties. Those dimensions in the video are mm. The size is similar to tip of your thumb.

2/3 of an inch.

Looks like they could be useful to attach coroplast as well.

The covers are made from PA 6.6 nylon?

Why would you attach coroplast to the covers?

That Hubcap/round plate is smoked polycarbonate. Plug is PA6.6 Nylon. I will use that plug to attach my front air dams, hubcaps, smooth undertrays, truck side fairings etc. So you can use it in almost anything, only your imagination sets the limits.

That plug is meant for 4.8 mm wide zipties and smaller versions can be also manufactured.

You could use them to attach coroplast without straining the coroplast where the zip-tie goes through it; and without straining the zip-tie by forcing it into tight bends (which is where they tend to break).

My apologies. I had switched to a video showing the caps, and mistakenly thought that's what the discussion was about.

I like these caps. Are they made from smoked polycarbonate?


Could coroplast be used the same way?

I'm still wondering why they made the holes so big, maybe to fit a wide variety of wheels, but it seems to me they could be much smaller and have less wind resistance. No zipties or any other type of attachment is needed, as long as the caps keep their strength over time.

Those holes are dimensioned so that plastic dont strecht too much when you assembly those to wheel. Also there need to be enough cooling surface area for the brakes.

If holes are smaller it wont work nearly as good or if they bigger some other problems occur. Same idea would work on your normal car wheels if wheels have 5-6 mm deep u groove on the outer edge like those truck wheels have.

Yes those FleXcaps can be manufactures also from smoked polykarbonate. Current basic version is manufactured from weather resistant ABS plastic

I dont think coroplast would work the best way because material needs to flex during installation process.

How much are those FlexCaps? Are they available here in the USA yet?

I'd like to get a set of those and see how well they do. Are there any documented reports on how much savings they provide?

I guess one could make their own here and give them a try.
