Q. about Omni-Block Swivel Pulley/Double

[poetmk]

Hello -

I've used the Petzl/prusik minding double pulleys in a 5:1 system alot but have never had a chance to use the Omni-Block Swivel Pulley/Double that Sherril is selling. Are they prusik minding as well? As good as the Petzl? Better? Worse?

thanks,

matthew

I don't think it is prusik minding. I use the single for the "M" system. It stays on my harness. The cheek plates are round, so it doesn't appear as though a prusik would tend. Awesome for the "M" though. Easy on & off.

I think this is what you're looking for ...

There's a good chance that Robert will be sharing some of his tips at Expo next month. Either at the climbing tree or in the TCIA Treeworker booth.

Thanks Norm and Kevin -

my video card went out and I finaly had a chance to get a new one and now i'm back online -


it looks very functional for whatever it will do - nice and compact. Norm, what is the "M" system you are refering to? Not up on all the tree-linguistics yet

peace,

Matthew
