Which "HANDLED" ascender has no sharp teeth

[Big Kawika]

OH YEAH ! Like I mentioned on an earlier post, by the book.

Be careful taking advice from arbos then.

 

[Big Kawika]

Copy that.

For rope ascent, I prefer leg power.

Rope walker systems are not known in all circles.

 

[Big Kawika]

So do I, although I do like to have a big, quick handling, easy to acquire hand grab with that many tie in holes like the isc hand ascender does.

 

[Big Kawika]

Yeah, that's what I've been told and what i can almost see from the few pics available. When i get the ISC device I'll try to send Closeup pics of the "cones" in question.

 

[Big Kawika]

Here are the "cone" shaped teeth that isc RH hand ascender is using. They project straight out 1/16 with a 2mm round base. Not sharp enough to catch or scratch a fingernail, yet pokey enough to sink into a rope. I hope this pic works for you. The whole device feels comfortable, lite, sturdy and we'll engineered. It glides up on blue streak real smooth. Locks up right now. Spring tensions are not too lite, yet not too strong. Every aspect of its usage can be easily done with one hand and thumb. Mission accomplished. Thanks guys.

This is the old ushba hand ascender I spoke of earlier. Pinching lever no teeth. Made of titanium.

Thanks...sounds like a good project

Who is teaching you about rope installation? There are several thowline shooters available. More important is understanding how to qualify a TIP..tie in point. Since this is for rescue you're likely going to have to consider a two person load on the TIP..plus amplified shockloads.

What books do you have?

The Tree Climbers Companion
Oh Rope
TCIA SRT manual

Last week I was going through my bucket of ascender/descenders. One tool that isn't used much anymore by arbos is a t-bar foot ascender. For your needs I think this would be much better than the rope walking systems arbos are using these days. RW's are complex and need to be tuned in order to work safely. A sit/stand setup would be easier I think. Then, change over to a descent system when you get to the victim. In that same bucket are a couple of descenders that can be adjusted for one or two person loads. Fast or slow descents. They've worked really well for me when I've climbed west coast big trees.

Tbar works well seeing most fire rescue crews I know of use a frog system with chest ascender. Rescue I know of are also are usually big on always having two attachments so a tethered twin hand upper ascender and chest ascender comply, then install descender when at height, before disconnecting upper or chest ascenders.

Always wanted one of these since I saw on storricks

Sorry, 2 years late to this post. Found it while googling on my own. Although I typically prefer foot and knee ascenders. Once in the canopy I still have applications where a hand ascender comes in....handy. The Wild Country Ropeman is my go to and the MK1 has a toothless cam similar to my Notch Jetsteps double toothless cam. I use the MK2 but noticed that it is pretty gentle on the rope due to the shape it is forged in. Hope this helps.
