Steel auto-locking descender with anti-panic function designed for increased durability within a work at height or rescue environment.
FEATURES :
- 2 safety features : the anti-panic function is triggered and stops the descent immediately when the user pulls the handle too abruptly; the descent is automatically stopped when the user lets go of the handle.
- Thick metal in high friction areas helps to increase the device’s lifetime in high use environment.
- The handle allows the rate of descent to be finely controlled and its 360 degree rotation facilitates its use. Its aluminium body is covered with a grip enhancing material. In addition, an audible clicking sound accompanies the handle’s rotation to help the user to identify the handle’s correct position.
- The device is locked using a metal button which prevents it from accidentally opening whilst ascending a rope.
- Movement along horizontal or low incline surfaces is made easy by simply controlling the cam with your thumb.
- The D4’s maximum working load is 240 kg. It is therefore suitable for rescues with a two-man load, without having to introduce additional friction.
- The D4 can be used with 10.5 to 11.5 mm diameter ropes.
