Grivel – Helix – Isskrue

Any gear you trust your life to should be simple and efficient. The Grivel Helix Ice Screw has a very basic design that’s easy to place and super strong. The Helix has a very positive first bite to get your placement started and a large knob so you can crank in the pro and move on. Unlike most ice screws, all of Grivel’s screws have reversed threads that increase their resistance against extraction for superior strength that you’ll appreciate when you’re on the verge of falling. The symmetrical design, with the knob opposite the clipping hole, allows for easy racking so they don’t take up your whole harness.

• Symmetrical grip
• Large knob on grip
