What do you need to ascend SRT with no arm use?

Just checked Wesspur and not available.

I did a search and still found them available on a few (mostly non-arborist) sites.

A few years ago, I tore a muscle in my right bicep right before receiving a Rope Runner. I refused to wait until I healed to try it out and was able to use my PMI chest roller to climb 'one armed'.

If you use a chest roller, it has to be below your life support ascender/descender. otherwise, if you slip or sit back you will have a fast trip down. The roller will tend your device on the way up.

Hey, Brocky! Thanks so much for producing such a gorgeous illustration! I'm away from my gear and unable to produce the photos or video that folks want to see. Your illustration shows the setup I would have produced if I had more time and talent. My harness has no buckle on the front, with the adjustability that provides, and it does have only one strap, (as suggested by @SomethingWitty) just because it takes me so long to produce work with the handy stitcher. It works ok in spite of all of this. The most important thing in your illustration is the strap up the back holding the clevis and pulley. That strap on mine is held by a knot in the webbing, and not stitches. I don't know which would be better, but mine hasn't failed to support me yet, and I have nothing to compare it to.

The position of the pulley is nearly perfect in Brocky's illustration, except on mine it might actually be attached a couple of inches earlier. It practically touches my collar bone.

So, Brocky, thanks again for going to all this trouble and saving my bacon as you have. I think if you were to produce this item as a complete package, with some kind of adjustability built in as to positioning the pulley, you might not be able to keep up with demand. Feel free to do so, if you have any interest.

Again, great job, and thank you very much.

Tim

I realize this is an old thread, but the PMI Christ Roller and Harness are available from onrope1.com. I spoke with the owner and according to him he purchased the last of RE’s supply! I received mine and they really do help for those of us that need them!

I LOVE mine! Works great for us older guys who have gotten rather beefier above the belt and thus top heavy. I ride my Bone right above the roller so it advances with no attention from me, and I can set back on it anytime I want to rest, all basically hands free. Ascent is via SAKA and foot ascender, or else with my DIY power ascender and DeWalt drill.

How's that work for you? Also was wondering, do you have a tether or some type of attachment between your bridge and your mechanical device? I am finding that the biner tends to ride against the front of the chest roller with the RR sitting on top of the roller while ascending. Not much of a problem until you sit back! I actually had one instance yesterday where it became lodged and i had to dislodge it before I could sit back and put my weight on the RR.

The power ascender works fine. I am really pleased with it. It comes on and off the rope so easy that it is very tempting to use it every time I climb, instead of getting some good exercise with the SAKA. I did make a long enough tether from the bridge to the BDB, so that the BDB would ride on top of the chest roller even when I am standing up. The climbing rope goes thru the roller but the tether does not. Of course, when I sit back on the BDB and take the pressure off the rope, I am no longer held completely upright by the roller, since the tether is not captured by it, but I can keep a little tension on the rope with my hand, or wrap it around the tether temporarily and still be upright. Also, I can still reach the BDB to manipulate it easily even with the long tether. When I get where I am headed up in the tree, I don't want the rope in the roller anyway if I am limb walking or moving around and need the flexibility. And I just remove the power ascender and hang it on a limb close by in case I want to go higher at some point. It took a few times to get used to all this, and it sounds a bit complex, but actually it is just second nature now and no more complicated than having to continually remove and replace the SAKA and foot ascender if using those. I will try to get some photos of the set up, and also I bought a used GoPro on eBay and am going to mount it on my helmet. I promised a number of people some footage of using the power ascender. One thing I am especially pleased with is the fact that the DeWalt does not make much noise if I want to climb in a park or other public place. A Wraptor sounds like a gas weed-whacker or small chainsaw; and of course for just rec climbing and those of us who are not working arborists, a Wraptor is an expensive luxury at the newer price of over three grand. I built this ascender, all new components and industrial compliant rating on the ascender part rated for two men at once, and including the brand new DeWalt heavy drill, for about $450. There are some Rollgliss r500 units on eBay, but a bit more expensive than I paid. I see one up for auction right now for $350. And several around $750. to $ 850. But that is still a LOT cheaper than a Wraptor for us amateurs and occasional climbers. Every time I get to feeling guilty for spending money like this on what is a hobby for me, I just remember both my neighbors. On one side, the guy just bought some kind of new Harley for over twenty grand and the other guy was bragging about his new fancy golf cart that cost almost six grand. And another fellow up the street owns two airplanes. This climbing, even with all the new gadgets, is a bargain!

I forgot your question about the tether binding. I have noticed the biner rubbing on the roller but have not had any issues with it catching or hanging up. It lays sideways against the roller because of the way it goes through the teardrop on the Bone, so that may help. I will try and take some photos later today; I was hoping to get in a climb this afternoon anyway when I finish work.
 
Try adjusting your rise of your harness so that when you are hanging you sit more upright. Also reduce your stride when ascending the rope. Take smaller choppy steps. When you start making long stride your center of gravity gets pushed back away from the rope.

Adjust your harness and perfect your form. Many times that reduces the need for gadgets and gizmos.
 
I've got a neck lanyard made from bungee cord. My Unicender is on my adjustable lanyard

Lanyard is snugged down short then the lanyard is attached.

The Uni ends up at the lowest point of my sternum like the chest ascended in other ascent systems. With this setup...and taking short steps like Donny said...I stay upright and don't need to use my arms very much
 
Hmmm...I watched the vid twice, on my phone, but didn't see the link. I wonder if the small screen clipped it off

The concept is easy enough to see. If someone could share the link I'd appreciate it though

I saw this a while back and have been constructing one myself, I would just throw out there that he is using toothed ascenders so there is no way for the roller tend his system downward, that might not be true for one of our multicenders using the same vertical order. Pretty trivial to throw on a high backup e.g. footlock prussic or lengthen bridge/add tether to put multicender above roller, but probably vital to do so.

Sorry, Tom, I forgot to add that you will need to view it on youtube and that the pictorial link is in the comments section.
