Ruined Tricams?

This does not look good. It appears as though the lables on my tricams have stuck themselves to the slings. These are nylon slings. The tricams have been stored in the trunk of my car, It has been hot here in the Northeast, but not wickedly so. I had an empty five gallon gas can in the back seat of the car. There were no solvents or other such chemicals in the trunk. In fact, the tricams were set into a storage bag. I was able to peel away one label from the back of the red tricam (pictured) the back of the lable was sticky. Other than the fact that I'm probably gonna die, any thoughts?

Yes as you suggest you are going to die. My other thought is I'd happily pay for the postage for me to perform thorough testing and to dispose of the responsibly. Cool

1) Don't store your gear in your trunk. If it gets really hot, you may find that your shoes begin to delaminate.

2) I've read that gasoline has little/no effect on nylon. "Testing done (by Allied Signal) indicates salt water, acetone, benzene, chloroform, freon, gasoline, kerosene, motor oil, mineral oil, paints and pine oil do not appreciably affect nylon and should not damage your rope. " - Bluewater. Parenthesis by me.

3) I doubt that the manufacturer would use any adhesive in the label that would compromise nylon. Those slings look like mine did after a while and I never stored them in a car trunk.

4) I'd use them. In fact, to ease your mind I'd happily pay postage.... dammit. I see Patto has dibs.

if you have any doubt, you can always have them re-slung, as far as the aluminum goes it should out last you.

How do you re-sling them? Just cut off the nylon and put some more or cord around the bar?

Some people cut off the old sling and resling with webbing tied with a knot. Much less expensive but obviously doesn't sit as well. If you do that, don't use dyneema and make sure to leave long enough tails for your knots.

I've heard some people say that they've cut off the old slings and used a drift to gently tap the roll pin far enough to slide in a new sling then gently tap the roll pin back into place. The manufacturer DOES NOT recommend this. Something about possibly fracturing the aluminum "ears". I dunno. We remove and reinstall roll pins in our machine shop all the time. And the manufacturer had to somehow insert the roll pins to begin with. So, I dunno.

There's a similocal guy to me that does a great job reslinging. I've had all my cams reslung by him and some of the people at my gym have had tricams reslung. He also makes some rad bigwall gear.

I just took my tricams out of my car and they too have the black label sticky and peeled off. I'm guessing they are stuck to the nylon.

In the manufacturing world many small pieces are glued together before they are sewn so the machine operator doesn't have to get his/her fingers into the way of the sewing machine needle needle. You're probably seeing the residue from that glue.

Likewise, most draws are glued together before they are sewn.

I don't have any tricams in my trunk, however, I will second that if you leave your shoes in the car, not only may they delaminate, but the rubber can become so bad that they resolers will not resole the shoes.

BTW, as you are leaving your softwear in your trunk, small note: if you have ever put a battery into your trunk, or a set of jumper cables. Then you are going to die.

really.

I think the idea is that automotive battery terminals are a common source of sulfuric acid containments. If you were to jump a car that had sulfuric acid on the battery posts, it could then be transferred onto the jumper cables. I would heed the recommendation, sulfuric acid is no joke, just a finite amount of acid can critically reduce the strength of nylon.

Dyneema is resistant to both acid and alkali. It is unnaffected by any ph value and is used for acid and alkali resistant gloves.
However since all the rest of your gear will be screwed this is only relevant as a correction to misinformation posted on the internet!

Interesting, I did not know that. However, many "Dyneema slings" are actually a hybrid nylon/ Dyneema sling. According to Metolius, Dyneema slings are often braided with nylon fibers to make the sling more supple so they are easier to sew. The only pure Dyneema sling that I know of is the new Petzl dogbones. There may be others, but my point is most slings have nylon in them somewhere which would be tanked by exposure to acid.

They all have some polyamid (nylon) in them including the Petzl ones which are sewn together with it.

You could take the most obvious approach and just continue to use them as is. They're fine.
Gasoline won't hurt nylon, but it will disolve glue, though I think it was probably more to do with heat.

Just wanted to thank all you folks who responded. After reading through these posts and talking to some climbing buddies I'm gonna cut my life short and climb on these. Slotted one yesterday in fact. However, I am no longer going to be using my trunk as a stowage spot. Thanks again,
