Hi there

Has anyone been climbing on the KROK and gear???
But most importantly have you taken a fall???
And how long was its overall lifespan, did it take a lot of punishment before it was retired???

The gear on ebay is a good price, but I am reluctant to go buying from people that I have not heard of before.

Your help is appreciated

I think it is a crock and you would be dumb to climb with plastic nuts.

I have seen plastic nuts and hexes in Australia. They work.

You see this is the problem.

There are a lot of contrasting opinions on this equipment and the brand. But I canít seem to find fact. I must admit I am leaning on the side of caution and donít think I will get the nuts or the cams.

But still would like to know of other peoples experiences with this brand and their products.

Thanks Again

There were some plastic (nylon?) nuts in the 1970s. Maybe made by Peck, maybe? I don't think they ever caught on, so to speak, but that may have had as much to do with the shape/design as with the material. Chouinard/Frost hexcentrics and stoppers pretty much revolutionized nut design at that time.

I don't know how durable plastic nuts would be. Harder material would be brittler, softer material easier to get stuck.

Nylon webbing works just fine, I don't see why nylon nuts wouldn't work as well. I have to say on a gut level it's scary as hell but prolly just cause it's something new.

I recall a lecture by a friend BITD on the theoretical
properties of plastics and so remain open minded,

there are aging factors

among other things...

not sure what's wrong w/ Aluminum?

Weight and cost I would think. Plastic has to be oodles cheaper. Aluminum requires an enormous amount of energy to smelt.

Hi there

Has anyone actually used this brand???

Some plastics are very strong for example I think they have made a plastic gun that fires real bullets.

Plastic can be very tough and rigid with a longer life span because they can take a lot more damage than aluminium.

But the whole reason I posted this feed is because I want to know if anyone has used or knows anyone that uses any of their equipment.

I remember (vaguely) someone on pull testing a cam to 110%+ the rated strength of a cam. Can't find it now, but am curious about this budget pro.

Nice bump....NOT.

BTW, I have 2 sets of these plastic nuts which I haven't used yet. A buddy bought the Aussie ones in the gear store in Natamook when we were over there and then insisted on using them for the next 2 years. They never set as well as aluminum ones, and took more skill to place.

The claim from Krok that their plastic nuts are lighter is only marginally true. The same size DMM/Wild Country nuts are real close to the same (tad heavier in aggregate) while some individualize DMM nuts are actually lighter.

Haven't had them out yet.
this just in

I would rather pay more for quality that's been tested repeatedly, and has a reputation of being reliable.
