The Petzl Chicane Auxiliary Brake: Final Thoughts from Me
For anyone operating in the specialized world of arboriculture or working at heights where mechanical ascenders are the norm, the Petzl Chicane Auxiliary Brake presents itself as a critical piece of equipment. As an experienced gear specialist with over a decade immersed in diverse environments from workshops to remote field operations, I’ve learned to trust gear that offers reliable performance and intelligent design. This particular device aims to enhance the safety and efficiency of single-rope techniques when used with popular mechanical Prusiks like the ZIGZAG or ZIGZAG PLUS. It promises a continuous, added braking action, crucial for controlled movements and security. My initial impression upon unpacking the Chicane was one of robust construction; the combination of aluminum, steel, and nylon felt substantial and precisely engineered, hinting at the quality one expects from Petzl. I had been exploring ways to adapt my existing mechanical Prusik setup for single-rope applications, and after briefly considering a more complex rigging solution, this specialized auxiliary brake seemed like the most elegant and direct answer to that need. It offers a palpable sense of security, a welcome feeling when working at elevation.
Real-World Testing: Putting Petzl Chicane Auxiliary Brake to the Test
First Use Experience
My initial testing of the Petzl Chicane Auxiliary Brake took place during a standard tree-care operation, utilizing a single static rope system. I was climbing a mature oak, a common scenario demanding consistent control and the ability to pause or descend with confidence. The installation process on the rope was straightforward; the openable side plate, secured with a triple-action release, felt reassuringly secure once closed. Connecting it to my existing ZIGZAG mechanical Prusik was also intuitive, clipping onto the upper hole as instructed.
The most immediate difference was felt during ascents. The added friction from the two integrated friction pins provided a noticeable level of continuous braking, which subtly assisted in managing slack and offered a heightened sense of control. This felt particularly beneficial when transitioning between anchor points or when carrying tools. While the user feedback I’d seen mentioned the OK carabiner being stiff, I found the Petzl Am’D connector, which I primarily use, slid smoothly into place, allowing the unit to function as a cohesive system. The ergonomic handle, designed for limb walking, felt natural in my gloved hand, facilitating smooth transitions without snagging or awkward manipulation.
Extended Use & Reliability
Over several weeks of consistent use, involving multiple ascents and descents, and even some controlled lowerings, the Petzl Chicane Auxiliary Brake has proven to be a reliable addition to my arborist kit. It has endured routine exposure to dust and occasional light moisture from dew, with no discernible degradation in performance. The aluminum and steel components show minimal signs of wear, even after extensive friction on the rope.
Maintenance has been minimal. A quick wipe-down after a dusty day is usually sufficient, and the design allows for easy visual inspection of the friction pins and mechanism. Compared to improvising with extra friction hitches or relying solely on a friction knot for descent control on single rope, this dedicated auxiliary brake offers a significant upgrade in safety and ease of use. The consistency of its braking action, unlike a hitch that can require constant adjustment, has been a genuine benefit, reducing the mental load during prolonged work periods. I haven’t encountered any stiffness or performance drop, which speaks to the quality of its construction and materials.
Breaking Down the Features of Petzl Chicane Auxiliary Brake
Specifications
The Petzl Chicane Auxiliary Brake is meticulously crafted from a combination of durable aluminum, robust steel, and resilient nylon. This blend of materials is crucial for its intended purpose, offering a balance of lightweight portability and hard-wearing resilience. It weighs in at a manageable 255 g, which is a negligible addition to a climbing system.
The device is designed to work with single ropes within a specified rope diameter range of 11.5 mm to 13 mm. This range encompasses most common low-stretch kernmantel ropes used in tree care and industrial work. The stated working load limit of 140 kg aligns with standard safety requirements for professional climbing and rescue equipment.
Performance & Functionality
The primary function of the Petzl Chicane Auxiliary Brake is to provide enhanced braking on single ropes when used in conjunction with a mechanical Prusik like the Petzl ZIGZAG or ZIGZAG PLUS. It excels at this by introducing continuous friction through its two integrated friction pins. This added friction offers a more controlled and predictable braking action, especially beneficial during ascents and descents.
Its performance is notably smooth when paired with the correct connector, like the Am’D or OK carabiner. The H-shaped cross-section of compatible connectors, along with the positioning ring of the mechanical Prusik, ensures that the rope glides efficiently through the brake unit during upward movement. This efficiency means less fatigue over a workday. The CHICANE also allows users to work in compliance with the ANSI Z133 standard, a significant factor for safety professionals.
Design & Ergonomics
The design of the Petzl Chicane Auxiliary Brake prioritizes both functionality and user-friendliness for professionals in demanding environments. Its openable side plate is a key ergonomic feature, allowing for quick and easy installation or removal from the rope without disconnecting the entire system. This is a massive time-saver and convenience factor in the field.
The triple-action unlocking mechanism on the side plate is a critical safety design element. It significantly limits the risk of accidental opening, providing peace of mind when the device is under load or in a dynamic situation. Connecting the Chicane to the upper hole of the mechanical Prusik ensures optimal leverage and performance, creating a cohesive and reliable ascender/descender system. The overall build quality feels solid, with precise machining and smooth finishes that don’t snag or abrade the rope.
Durability & Maintenance
The Petzl Chicane Auxiliary Brake is built with durability in mind, featuring replaceable friction pins. This is a significant advantage, as these pins are the primary wear components and can be swapped out when they eventually show signs of degradation, extending the overall lifespan of the device. The use of aluminum, steel, and nylon suggests a design intended for long-term, heavy-duty use in challenging outdoor conditions.
Maintenance is straightforward. Regular cleaning to remove dirt and debris that could impede performance is recommended. The openable side plate makes it easy to access the rope path and the friction pins for inspection and cleaning. Unlike some friction devices that require complex setup or frequent adjustment, the Chicane offers a set-and-forget reliability, with its continuous braking action requiring minimal user intervention once correctly installed.
Accessories and Customization Options
The Petzl Chicane Auxiliary Brake itself is designed to be an accessory, specifically augmenting the functionality of mechanical Prusiks such as the Petzl ZIGZAG and ZIGZAG PLUS. It requires compatible connectors, such as Petzl Am’D or OK carabiners, which are sold separately. The inclusion of a positioning ring on the mechanical Prusik is crucial for its effective integration with the Chicane.
While the Chicane itself doesn’t offer extensive customization in terms of altering its core function, the availability of spare friction pins is a notable aspect of its long-term usability. This means that minor wear doesn’t necessitate replacing the entire unit, making it a more economical and sustainable choice for frequent users. The compatibility with specific Petzl connectors ensures a unified system designed for optimal performance.
