Lockjack mods?

Yep your points are correct, I have had all 3 art devices, my preference is the lockjack on taller trees, my postioner on most 15ft to 30ft, which is on a 20ft lanyard, for take downs, so I don't need the full length of rope etc, I abseil off the spike with a fig 8 descender for the final fell.

I do love my lockjack, it is so much easier than prusik work.

Hey, tuttle! Thanks for the response! If you don't mind, I have a couple of follow up questions. You say the Lockjack "is so much easier than prusik work". Why is that? Is it just that the Lockjack operates so much more smoothly than a hitch? Or the fact that it can be removed from the rope midline, perhaps? Or some other consideration I have not thought of? Is the Lockjack able to be put on the rope or taken off relatively quickly and easily, or is it a cumbersome process?

Also, you said you've used the Spiderjack, but made no comment as to how you felt about using that device. So I was wondering how well you liked the Spiderjack, or not.

Sorry, I went way beyond the two questions I said I was going to ask. Thanks for any response you choose to give.

View attachment 32262 I connect my lock Jack to my saddle with an oval link.
This allows me to insert a bight thru and use my F8 to control long descents and spare wear on clutch, with hands off stopping.

Hello, William! The setup depicted in your photograph looks absolutely brilliant! Elegant in its simplicity. The Rock Exotica swival pulley is attached to the green rope, which represents the rope bridge of your saddle, correct? The photo may be displaying in an upside down orientation on my device.

I'm wondering if the use of the Figure Eight in the way that you do allows you to climb with the Lockjack using Single Rope Technique (SRT)? I thought that I had read somewhere that some folks were using the Rope Wrench in combination with the Lockjack to enable Single Rope Technique (SRT) climbing. Your use of the Figure Eight where it is would create a much more compact system for SRT than the addition of a Rope Wrench, assuming that it works. Again, just brilliant, even if all it does is prolong the life of your Lockjack when used in DdRT (Doubled dynamic Rope Technique).

Thanks for posting the great photo, and for any response you choose to give.

For single rope you need a hitch as previously posted.
Else the LJ will not grab.
The F8 will work to take load from the clutch.
 
The lockjack is a smooth ascender no matter what the weather is doing, unlike a prusik which when wet changes completely.

It's super easy to remove and setup on the rope, just a few turns of the screw.

I only messed about with the spider jacks, had a few that I bought, cleaned and sold, because they are not midline attachable and are bulky, I thought against them.

A lockjack is the best thing to use, just takes a bit of getting used to, and you need to completely understand every component.

Thanks for this terrific review of the Lockjack. It points up specific advantages of the device over a hitch based system that I have not seen expressed by anyone else before, especially in your first paragraph.

Much appreciated.

Thanks, with the lockjack it's much better to have someone who knows the device inside out.

I have had one for 3yrs, but the first one I bought I sold on, because I could not get on with it.

When I bought my next one, I perservered and used it no matter what, I pushed my thinking to get it spot on, its a real good tool, but like I said, best to have someone who knows.
