OR1 Mitchell Climbing System

• The Mitchell Climbing System is a fast and versatile rope walking system.
• Since both ascenders are in the climber’s hands, it is easy to “thumb the cam” allowing for easy self starts and down climbing ease.
• OR1 suggests CMI Ultrascenders because they have straight teeth on the cam which allow for easier operation.
• A practiced user can descend as fast as they can ascend.
• Rope is used for the ascender cords so the system works properly in the chest rollers.

• This system includes:
  • 1 – OR 1 “H” Chest Harness (F09)
  • 1 – Double Chest Roller
  • 2 – CMI Ultrascenders – short (ULTAS02)
  • 1 – Long cord (F07)
  • 1 – Short cord (F08)
  • 1- Tether (8mm loop that connects to the lower Ultrascender and then to the seat harness)
  • 1 – OR1 Stiff StepTM – Right (F01)
  • 1 – OR1 Stiff StepTM – Left (F01L)

Optional Hammock Chest Harness
The ultimate in comfort when using a chest plate and roller. A great upgrade for your Double Bungie System or Mitchell System. More support than the H harness, the hammock actually cradles the climber.

Measure around your chest, high under the armpits and high across the front of the chest, leaving enough space to be able to take a deep breath. Choose the measurement below closest to that number, without going over the next size up. Please do not use clothing size, it is not the same sizing.

Note that the measurements below are ALL the way down to ALL the way opened up. A chest roller typically takes at least 8″, so if using a roller make sure to add that to smallest number below. You do not have to subtract it from the largest – that is with the chest strap all the way out.

Shoulder buckles are now attached to the harness straps.
