finger traps

question from pondering
when using a throw line in a tree, would it be possible to push an end of the climbing line into a chinese finger trap or something similar- something that cinches when being pulled, then run the line up the tree?
rope setup: throwbag->throw line->finger trap->climbing rope (pushed into fingertrap).
as the climbing line is pulled into the tree, the finger trap tightens around the rope pulling it up, eliminating the chance of the rope getting caught in a crotch.
 
I can't believe you asked that question...I have been thinking about that for a few weeks now...even researched them with Google...not too much out there I could find. There may be something related to pulling electrical lines thru conduit maybe? With a small trap on one end and larger one on the other, it seems you could join 2 different size cords...a "Chinese sheet bend"?

Yes there is something out there for pulling wire through conduit. Never used it tho as you ahve to back it up with tape. If you don't mind the hassle, you might chect it out. My electrician friends are checking into it for me.

Good luck!
 
I took a plastic nose cap off a large bottle rocket, poked a hole in the tip large enough to feed my 1.75 Zing-It through, put a couple of half-hitches on the rope, and placed the cone over the end of the rope. It still did not allow me to pull it through a tight Elm crotch...

You could take a few inches of jacket off the end of your 5/8 or 3/4 Double Esterlon, Stable Braid, etc. and fashion your own "chinese rope cuff", and it would be more flexible than the plastic cone, but the attachment to your throw line would be a bit bulkier (than the cone, but certainly less than to your rope directly) so I don't know how ultimately effective it would be.
 
There is another thing we used to use when pulling in wires if we didnt have any "pull fingers" we would use a pulling hitch (well thats we were told it is called) its simple to tie......

Take 4 full wraps going away from the tail of your climbing line with the throwline, then take the tail of the throwline back around the first wrap you made, then tie at least 3 but no more than four half hitches around the climbing rope past the last wrap.

OR

We would just tie one over hand knot about 8 inches down on the climbing rope with the throwline tail and then twist half hitches back up toward the tail of the climbing line until we ran out of room. These never failed me when I pulling in Any cable whether it was a phone cable the size of you thigh or a fiber optic cable smaller than your pinkie. Good luck


If your deadset on a pullfinger (also called a beckett, sock, finger, chinese finger, and a cablefinger) look into some lineman supply stores and companies called LEMCO and BECKETT they make their own.
 
Fresco has a finger trap fid that they use with the Guardian cabling system. It would have potential.

Another tip is to use one of the spring dor bumpers that you screw to a door or the wall to keep the doorknob from busting a hole in the wall. Slip the throwline through the small end and pull the rope into the "fid" that is formed.

Another one is to use a small plastic soda bottle. Same idea but tie a stopper knot to keep the rope inside the bottle.
 
For the murrelet nesting survey we were hauling an 11 mm static line with a throwline over a branch at about 175'.

We tried out a sash cord puller, made for the 3mm line used to run drapery traverse rods. It's a hollow metal tunnel device, with a tapered plug thru its center, sort of like a bell clapper, that crimps down on the line when tensioned.

I'll try to find it & take a photo. We ended up wrapping Black Line throwline around the small eye of a figure eight, climbing up on a stump, then jumping off the downhill side.
 
I saw that Gaurdian Cabling (Fresco) system at TCI Expo. If you could get the rope trap without the fid it would easily handle your climbing line. Me...I'll stick with a clove hitch and half hitches for now but who knows what the future holds.
 
I used to work in the computer industry, mainly networking and point of sales systems, pulling cable was one of the many oh-so-not-fun tasks. What you're thinking of is referred to in the industry as a basket-Type pulling grip. Greenlee( www.greenlee.com ) is one of the major companies that makes them. I'm not sure how well it would work for pulling line into the canopy, but they're the bee's knees vs trying to tie or tape the pull line to wiring.

I bought a couple of those types of pullers a few years ago. I thought that with a little creative mutilation they could make rope splicing easier..........

........On another note I really like my Brion Toss splicing wand. Use it all the time.
 
Hi guys,

I've spliced a little eye in my zing-it, put a small keychainbiner throug on which my throwbag is clipped.
If i need to pull up my climbing line i unclip the throwbag an clip in my climbingline. It will never get stuck in a tree, the biner is so small the eye from the climbingline almost doesn't alow the gate to open.

The throwbag is clipped in not using the ring but through the sling this too prevents the biner opening.
 
A friend of mine showed me a while ago a finger trap thingy he made using that yellow hollow braid they sell at hardware stores for 15 cent. About a foot long with an eye splice in one end and loose at the other. I remember it being a little awkward to stick the rope into it. it worked as I recall. I didn't quite get the point of it when he showed it to me. its funny how different people can invent the same thing with no contact with one another..
