Buy the Petzl I'D Online

The Petzl I'D is a Self braking descender with an auto locking function to allow hassle free stops to be made with the security of an anti error catch to reduce the risk of accidental incorrect installation of the device.

 
The Petzl I'd has the following features:- 

• Anti-error safety catch reduces the risk incorrect installation of the device reducing the risk of an accident 

• Anti-panic cam locks the device onto the rope if the user pulls the handle too hard.

• Handle has a locking position for work positioning while on the rope. 

• Device can be used to create a reversible hauling system.

• Swinging side plate can be opened without total disconnection of the device to reduce the risk of dropping the device when installing or removing the device from the rope. 

• Swinging side plate creates efficient means for passing intermediate anchors.

• Available in 2 sizes:

  • D20 S (gold) for work on most industrial ropes.
    For rope diameters 10 to 11.5mm.

  • D20 L (Red) for arborist and rescue ropes.
    For rope diameters 11.5 to 13mm in.

The I'd locks in an uncontrolled descent and will even lock if the handle is accidentally pulled too hard.

The benefits of the above features are increased safety and less time in use and preparation.

The Petzl I'd offers the same applications as the well known Petzl Stop. With the addition of the features listed above another advantage of the I'D is that when used for short ascents of a rope it far out performs the Stop. The rope runs much more smoothly when ascending with the I'D than with the Stop. 

Below are two tables outlining the shock loads and slippage results of the Petzl I'D under the following test conditions: 100kg mass with a factor 1 fall on a 2m length of rope the results will vary depending on the type of rope used.
