Great price on small load-bearing 'biner

**Nest** · 12-15-2008, 02:34

I have seen the beding actually happen with my Camp Nano biners. I didn't wrap the webbing right, and the biner wasn't centered on the tree, but slightly to the side. This made the webbing pull the top of the biner toward the center of the tree trying to center itself, but couldn't because I wrapped the webbing around the tree twice. As I was laying in the hammock I happened to look at the biner, and noticed that it was twisted and bent enough to have opened up. Went back to normal and hasen't hurt the biner from what I can see, but I definately wan't the overkill on the main biner for that reason. I will point out that I use a structural ridgeline, so I put more force than someone who doesn't Like with a Speer or slap strap setup.

I have quite a bit of experience with these 'biners, including using them extensively climbing, and I'd have to say that I am skeptical of your interpretation of what happened. The open gate strength of the nano is 7 kilonewtons, or about 1500 pounds force. I am having a hard time envisioning a way you could load the biner that would produce enough force to actually twist the spine enough to open the gate.

My theory: The wiregate on the nano is wider than the spine itself, so it's far more likely that the wire gate itself was pushing or twisting against the tree in a way that opened it without substantially deforming the aluminum spine of the carabiner.

This is something climbers deal with on a regular basis - when you're building an anchor a couple hundred feet off the deck, you have to be really careful about crossloading a biner or putting it in a situation where its gate will rub against the rock, because you want to prevent that gate from opening.

Could be. I was looking at it above my head at an odd agle and partly from my peripheral vision slightly out of the top corner of my eye. In other words, all I saw was that the gate was open, and things weren't lining up. Nice to know that it wasn't anything close to being bad.

i bet that's what happened too, the gate probably had pressure on it sideways.

biners flex too and that doesn't mean they are about to snap (although i know a couple folks who have broken climbing rated biners during climbing falls). there is clearence between the nose and the pin (or the end of the wire loop in the case of a wire gate) force causes the biner to flex to the point that the gate comes into contact with the nose and the flex stops, but they are somewhat flexible. i'd say the biggest difference between the nano and the 500 kg biner is the gate itself, they are probably alot closer to eachother with an open gate strength than they are closed gate considering the weights. i also don't know that i would worry about a little flex, especially in a non-life threatening situation.

those biners appear to be identical to the treklight ones (probably where they got them, especially considering the engraveing treklight has on the side along with the exact same rating and design) and i haven't heard of any problems with the treklights and they've been used in that application for awhile now by several hf members. they are somewhat lighter than the nanos too aren't they? but i guess if you're using an adjustable webbing suspension with 25+ feet of webbing + adjustment hardware and 2 biners you obviously aren't a gram weenie so a fully rated biner is still a reasonable alternative. folks seem do seem to like the treklights though.

I suspect that 1100 Lb biners should do just fine.

where did you get biners rated to 600 or 300, i never see ratings on the side of accessory biners, just "not for climbing"

Count me in on 4 biners.

I'd be interested in 6 in a group buy. I've been using 2 Treklight biners for over a year now with good results.

Me too. I used to be a 160 pound weakling and now I'm a 210 pound weakling and it holds me up. Mule

Does anyone know if multiple colors are available in a group buy???

**Cannibal** · 12-17-2008, 13:24

I WANT SOME!!! If there is a group buy, I'm down for 6.

If these are the same as the TL biners, I'm not worried in the slightest. At least not for the way I hang, which is pretty much the same as most using a buckle system of some sort. I've got well over 300 nights (probably more) hanging with the TL biners. When out in the woods where I belong, they are wrapped around a tree, rock, pole, etc... When at home, they just clip to my attachment point and the hammock in a straight line. No problems, no bending, no catching, nothing but a good night's sleep.

For the record, I ain't no skinny kid!
