In reading the rule book, what is meant by "No two piece or welded "D" ring style adjusters for Arm restraints?

Does Crow, DJ Safety, etc, do they have these forsale in Summit racing, or how do I avoid purchasing these arm restraints?

TIA

Those who said it could not be done, should not stand in the way of those who are already doing it!

Search the forum under wrist restraints - there was a discussion about the definition of this rule and you should find it that way. I purchased restraints from DJ and sent pics to tech and they approved them.

iirc the D ring adjusters (like the old chin strap adjusters on a m/cycle helmet) where there are 2 D rings side by side, with the D's made with a loop of 'wire' welded to close the loop, is out.

Certainly sir; a lick of salt, a sip of gas and a twist of Lemming. More Lemming sir?
Just a squeeze.

A Squeeze of Lemming it is sir.

Not to sound dumb, but are there any arms restraints out there that AREN'T fastened with Velcro? No offense to whoever designed the stuff, but I really don't feel like trusting  any body parts with some fuzzy plastic...

I use DJ Safety arm restraints simple as that. Check with Kiwi Steve but they have to be approved.

Yes, this was discussed at length on this board previously.   Arm restraints with two welded D-rings CAN be used, but the D-rings can only be used as attachment points - with the strap passing through both of them together, rather than through one then the other.  They can NOT be used to set/adjust the length of the straps that restrain your arms as it was discovered that (in a high-G impact) the straps can slip through them and allow your arms to come free.
Rather, the adjustment of the straps' length MUST be accomplished by threading them through a flat, figure-8 shaped bar - like a smaller version of the flat bars that are used to securely adjust the length of shoulder harnesses.    Anyway, the key is adding the flat, figure-8 bar.  Kiwi Steve did have a bunch of them.
