Interesting rigging solutions

[Tom Dunlap]

This company makes gear for the fishing industry. There might be some pieces that would work for tree rigging.

THe solutions they've designed are clever even if their gear might not be an exact fit for arb work.

Asano Metal Industry Co., Ltd.

makes me wonder about the possibility of rigging rings that are mid-line compatible for adding redirects to a fishing pole that is already set up, or that rollers could be incorporated into something like the safebloc. I know that the point is to have an increase in friction, but it is a lot of work to pull a 5/8" or 3/4" rope back through that thing.

Exactly

I like the concepts but they are scaled too big right now

Maybe throw them in the dyer at the laundromat on high heat?

I've not seen these used in tree work, but they do exist for sailing (i believe is the common use for them)

Somebody has tried them, there was one for sale a while back, it would only have one bearing surface, unlike rings.

Thought the Sheaveless Block looked interesting, but being not midline attachable it probably can’t do anything better than a ring. Still, kinda neat.

They only make two sizes of those, both for small diameter cords.
I use one to route my knee ascender retracting reel cord.

That is super neat!

Yes, the pictures are a bit misleading, they’re quite tiny. If they made one for 1/2” rope I’d try it. Ronstan seems to make a lot of quality sailing gear for a few bucks less than the Harken equivalent.

The best practical key chain out there then!

David Driver tested them. Probably in the archives here.

Reminds me of an ABR/Notch radius ring.

Don't know if it's too big but it maybe could replace a bridge ring for those who wants more radius

I picked up two of these danik hooks off amazon and used them with some success for a solo, remote release retrieve, branch lowering setup. You can pop the gate off of it easy. Attach hook (with rigging line) to your branch with sling, lower branch to the ground, give it a good shake to detach the hook (there was another thread on this forum where someone else explained this concept much better) and you can pull the rigging line and the sling back up to you in the tree.

It's got a toothless cam rope grab and has been plenty strong for dropping small limbs. I would say my biggest has been in the 100lbs range. Putting it on the line is a little tough, too bad it's not mid-line attachable.

the fine print says *not for overhead lifting* so you may not get much warranty support if they break or slip on you

Guys used to use rings at solid points or plan ahead differently. As for midline they’d run blocks or clevises for mid line spots they come in smaller but heavy duty enough pieces
