Great little pulley biner combo.


  • Works great


  • Very small biner
  • Bottom of the biner is a challenge to use

The revolver is a great piece of kit for top roping and glacier travel. It cuts down on rope drag, and it is essentially a built-in pulley, which gives you a huge mechanical advantage especially as a secondary part to crevasse rescue kit.

Only complaint is that it won't work with a Petzl Tibloc. Prussicks seem to go fine.

Very durable and while the gate opening is a bit narrow, it is easy enough to figure out.

I'm guessing the enlarged top is too big to fit the Tibloc?

Found these great biners from a friend!!!


  • Cuts down rope drag!!!


  • Cost

Greatest biner ever made for cutting down rope drag. The little roller works great for rope drap on routes that zig zagĀ  or over ledges. Use a little longer runner on your quickdraws and never worry about it again. Also the locker works great for setting up a top rope on fixed belays.
