Whats your favorite light duty pulley ?

Flying squirrel what kind of weight can go in to the xrr friction saver with 2 rings?

I strictly us this set up for light rigging. Everyone knows what Xman says about the strength of the rings. So the cordage is the weak point. The cordage I used to make them is 1/2 stable braid with a breaking strength of slightly over 10k (working load of 1000#). The rope I use with the FS is 16 strand safety blue hiVee with a breaking of 7k which forces me to limit my loads to 700# or less (mostly less). They are great for pruning, easy to install and I dont have to go back and get them. I have not seen any adverse effects on the rope or the rings. If I had the money and distructive nature I would send it out with a piece of rope and see exactly what the breaking strength would be as a system (because as we all know, thats the important number).
 
Flying squirrel if your using your x rigging rings as a top rigging point then lowering wood in a traditional manner shouldn't you limit the piece size to 500 pounds beings the x rigging rings are being acted on by a 2 to 1 while your lowering wood? Obviously the rings create some friction so it isn't a true 2 to 1 but close enough for me.

Never mind it donned on my little brain your using the rings in a basket doubling their strength!
 
No problem. But keep in mind. Xman suggests 3 rings at the terminal rigging point. With that in mind I rarely break 300 pounds when using them. And normally only in pruning situations. For removals I still use a block because retrievablility is a mute point in most situations I face.
 
Omni block on a tenex sling has worked well for me. Can be remotely set and can handle their fair share of weight at a small cost.

I picked up this CMI for light duty rigging and redirects. All my ropes are 9/16" and 5/8" right now. It has a 4" sheave diameter, and rated 70kN MBS... but I don't think I'll push it hard. Sideplates are pretty thin sheetmetal, but at least it's stainless steel.

It looks like a nice system but doesn't that poly limit you?
 
It only looks like poly. It's actually 5/8" nylon with 11,200 lbs. ABS and I believe the MBS is well over 9500 lbs.
The orange color makes it look like the hardware store poly they sell for boats. Pick it up, and you instantly realize that it's not... it's heavy. Four process hard lay. I can splice it, but it's a bit tougher than other 3-strand ropes I've spliced. It fights you all the way. It's very tough stuff, though. If you look close, you can see the red tracer specks that run through it.
