Nomic (1st Gen) umbilical attachment point mod

MOD #3 Petzl Nomic Umbilical Attachment

 

I still have fixed feelings about umbilicals, but like many of you I don't want to lose a tool when I am 2-3 pitches or more of the deck. It would mostly hurt my wallet. I got the idea from a guy with a par of new Nomics, apparently there is a hole where you can attach cord or even coated with like I did, but you will need to drill the hole if you have the original Nomics.

MOD #3 Petzl Nomic Umbilical Attachment (with BD Umbilicals attached)

 

 

I designed the attachment point to fail at around 170 lbs., the reason being is that I don't want a tool to smash me in the face after falling. If the tool is placed solid enough and I fall it should stay in the ice and I will hopefully be able to retrieve it later.

 

It will also keep one honest since you won't not be able to weight the umbilicals since the swag will eventually fail which will send you plummeting to your death! After all the umbilicals are meant to save a dropped tool, not to hold a fall!

That is BY FAR the best umbilical attachment I've seen for the Nomic. It looks like the wire and biner sit far enough away from your hand to not get in the way.

 

Care to explain the process in more detail?

I was belaying a fellow who fell onto his umbilical and it held. Without that, he would have cratered. food for thought. maybe umbilicals should come equipted with screamers.

But sometimes they do hold falls, which I think is nice.

Easy mod and worth the effort Swaging wire is one way. Or you can decide how much weight load you require by cord size and be able to check and replace it easily. Almost any other method is better than the two factory versions (old or new) imo.

Easy mod. This is from last year. Swaging wire is one way. Or you can decide how much weight load you require by cord size and be able to check and replace it easily. Almost any other method is better than the two factory versions (old or new) imo.

Clickable.

Thanks! I like my mods to look as close to factory as possible. I did play with the location of the wire so it the biner on the umbilicals did not get in the way. I botched the first one, but you can't tell when the hand rest is on.

 

All you need to do is drill a hole in the aluminum piece that holds the adjustable hand rest. You will need to find a small swag or reduce the size by grinding it down which is what I did. Don't make the hole too big and don't get to close the the hole that is for mounting the hand rest. You will need to remove some of the plastic from the hand rest so you can slide it on easily when the wire is attached. If you use cord this will be easier. It is a fairly easy mod, but takes time to get it looking nice.

 

You can experiment how hard to swag the wire and this will determine if you want it to break free under load like I've done. This is really personal preference. Others have mention that your tool could hold a fall, however I will never rely on an ice tool to hold a fall that's what screws are for!
