The Petzl I’D series offers a versatile, durable descent control device that can be used for so much more. By point of design, the I’D is a self-locking descender and belay device. The user articulates the handle to control the speed of the descent or lowering, while if the user panics and pulls too hard, the load is auto arrested by the I’D’s anti-panic feature. The same occurs if the user lets go of the handle. To take the safe use precautions a step further, if the device is loaded backwards, an internal safety catch makes progression impossible. A diagram on the device illustrates proper loading technique. Outside of it’s primary function, the I’D is also quite useful as a progress capture in simple mechanical advantage systems, as a progress capture in system tensioning and can be used in ascent systems such as the RAD or rapid ascent/descent.


  • The Petzl I’D is available in a “small” NFPA “T” rated device, for use with 11mm (7/16”) ropes and in “large”, an NFPA “G” rated device for use with 12mm (1/2”) ropes.
  • Both device feature a pivoting cam which locks on the rope via compression when the handle is placed into the lock position.
  • No tie-offs are needed. The handle also features a horizontal movement button which allows for low angle and steep angle access without having to work the I’D handle.
  • Both versions of the I’D are available in tactical color sets as well.
