Petzl D021 RIG Industrial Rescue Descending Protector with AUTO-LOCK System for 200 kg Rope Work

The Petzl D021 RIG is a rope descending protector designed for industrial rope access, rescue, and technical work at height. Its defining feature is the AUTO-LOCK system, which automatically secures the rope when the handle is released, allowing the user to work hands-free without manipulating the handle or tying off. This device meets multiple international standards including EN 341 type 2 class A, EN 12841 type C, and NFPA 1983 Technical Use, making it suitable for professional environments where safety and reliability are critical. With a maximum working load of 200 kg and compatibility with 10 to 11.5 mm ropes, the RIG offers robust performance for both solo and team-based operations.

Features and Construction

The RIG incorporates several design features that improve ease of use and operational safety. Its construction uses aluminium, steel, and nylon to balance weight with durability, while stainless steel wear plates protect the rope friction zone during repeated descents.

Material and Build

The main body is made from aluminium for a lightweight profile that reduces fatigue during extended carry. Reinforced stainless steel wear plates are placed in the rope friction zone to withstand the abrasion of frequent lowering and raising operations. The handle is constructed from nylon with an ergonomic shape for comfortable grip, and it automatically returns to a storage position when the rope is removed from the device, minimising the risk of accidental snagging on the harness.

Size and Practical Fit

The device accepts ropes with a diameter of 10 to 11.5 mm, covering common industrial and rescue rope sizes. Its compact form factor attaches directly to the harness via a standard connector, and the mobile side panels feature safety gates that allow the rope to be installed without unclipping the device from the harness, simplifying passage at intermediate anchors during a traverse or multi-point system.

Uses and Placement

The RIG is primarily intended for industrial rope access, rescue scenarios, and worksite positioning. Its dual descent modes and AUTO-LOCK system enable both controlled lowering and stable hands-free work in a single device.

Event or Professional Use

In rescue operations, the 200 kg working load capacity supports rescuer-plus-victim loads within the rated limit. The handle release mechanism automatically locks the rope, preventing uncontrolled descent while the rescuer manages the casualty. Compliance with NFPA 1983 Technical Use and EN 341 type 2 class A ensures the device meets recognised standards for fire and rescue services.

Everyday Home Use

For arborists, building maintenance crews, or industrial inspectors, the RIG provides everyday controlled descent and re-ascent capability. The cam can be operated to tighten the rope during short ascents or to tie off using a climbing technique, making the device practical for routine work positioning without requiring a separate ascender for every task.

Benefits and Buying Value

The RIG combines multiple functions—descending, hands-free locking, and rope management—in one unit. Its durability features and approved certifications provide confidence for long-term professional use.

Reuse and Low Maintenance

The stainless steel wear plates extend the lifespan of the rope friction area, reducing the frequency of component replacement. Simple inspection after each use—checking for wear on the rope contact points and confirming the AUTO-LOCK mechanism operates correctly—keeps the device in working order without complex maintenance procedures.

Why Choose This Product

The Petzl D021 RIG stands out for its integrated AUTO-LOCK system that eliminates the need for additional knotting or backup devices when positioning hands-free. The combination of lightweight aluminium construction with durable steel wear plates, along with multiple international certifications, makes it a reliable choice for professionals who demand both safety and operational efficiency in a single descending protector.
