Petzl - Am'D TriAct

I have a matched set of these in a kind of coppery color and they look and perform beautifully. I have noticed the "sharp" edge on the locking collar and for this reason I don't use them in applications where your supports regularly become slack enough to drape down and catch, like with a Texas clmibing system.



I was pretty surprised to read these reviews and find that no one mentioned the primary reason to opt for this style 'biner - the non-snag "nose". I guess most of us take this for granted, but for those newbies not familiar, many carabiners fall into the "wire gate" category. This means that the "nose" of the carabiner has a notch to catch the wire. I only know of one wire-gate carabiner that doesn't have this notch. So when a wire-gate 'biner is opened, that ragged notch will snag nearly everything possible (besides the wire it's meant for) when detaching from your saddle or your current configuration. Not the end of the world, but bad enough so I created a separate place on my harness for all non-snag biners. If I'm in a particularly tough predicament, I don't want to have further frustration.



I strongly recommend "smooth" carabiners to every climber, especially these. I have not had any of the problems described in the other reviews, but of course debris jamming can happen to any device.



One particular application is with an eye to eye prusik, which I use frequently because of the friction knots I choose. The smooth end slides in and out of the small splices quickly, with no hanging up or wear on the spliced eye.



I have to qualify my rating on "Type of Use" by saying that some certified arborists to whom I have spoken only use steel 'biners. In my opinion I feel this is a totally versatile piece of gear, to be used in all normal life support situations. But since some tree service companies require their personnel to "stick with steel", I give it a 4.



"Frequency of Use" a 4, only because I have so many frickin' carabiners, I like to rotate thru them and experiment.



I find the action easy and the shape ergonomic enough to be opened easily with either hand, although in the winter insulated gloves make it tricky. Even young people with smaller hands should be able to do it once they have experience. (Not so with the "William", which is very wide and you need big hands to do it one handed without struggling.)



I have tested this carabiner by hanging on it and then operating the gate to see whether or not there is any appreciable flex that distorts opening/closing under load. My full gear and I weigh about 180lbs (not including chainsaw) and there is no discernable distortion of normal operation under that load. I have tested other 'biners and this is not always the case.



Once every couple of years I wash them in soapy water, blow them dry with compressed air and then hit them with either WD40 or Remington light machine oil. Beauty mate!

Work OK

I've been using a pair of these and a pair of Petzl William TriAct carabiners (same gate mechanism, pear shape) since I started climbing 2 1/2 years ago. They seem to work fine for me. Any piece of gear has quirks that you need to know and adjust to, and these are no exception. I have sometimes cut my hand on the gate while climbing DdRT - when my body is in certain orientations my hand brushes the carabiner while hauling down on the rope - so I've learned to orient the gate toward my body as Moss describes. I have also had bits of bark catch in the closing mechanism and prevent locking, but it's hard to imagine any carabiner would be completely immune to this; I climb a lot of white pines and often have to wend my way between a lot of dead branches. I have found that sometimes the gate will not fully lock even in the absence of debris, so I've learned to check carefully. I suppose it's possible that the gate could open by accident, but I've never had this happen, even in tight places. On the whole I'm content with these, and don't feel any urgent need to replace them anytime soon.

My main biner

This is my primary biner. I clip in with the gate opening down and the gate facing in. This reduces the chance of branch or rope contact with the biner. I still regard it as a tri-action since you have to move the sleeve down (in my preferred position), then twist, then open the gate. It is only double locking since after the first two moves it is not locked. I don't think there are any triple locking biners available. Have yet to have the gate fail or open unexpectedly in 2.5 years.

Not triple action.

When you read the name of this carabiner, you assume it means tri (triple) act (action). It is not. There are two actions. The barrel slides up, a move that is a bit difficult to do one-handed, and then you rotate the barrel. The gate will now open. Two actions of the fingers to achieve gate opening.



The barrel is metal. That means a sharp edge at the top. I have personally never been cut but I have heard of a few reports. I have heard a few reports of the space at the top of the barrel jamming from bark fragments too, but that might be a result of climbing corky-barked trees or scaly barked trees.



I have bent the barrel at the top making it dysfunctional. The carabiner rubbed against a branch as I climbed past it.



I do not think the carabiner is cheap or weak. I'm just not sold in its design for active tree climbers.
