After weeks of consistent use, the Petzl Zigzag Plus Descender has proven to be an exceptionally reliable tool in my arborist kit. The steel construction contributes significantly to its durability, and even after countless repetitions, there are no discernible signs of premature wear on the main components. The separated and curved side plates seem to do an excellent job of protecting the rope and the device itself from excessive abrasion. Maintenance is straightforward; a quick wipe-down after a dusty day and occasional checks of the sealed ball bearings in the pulley are all that’s required. Compared to simpler, purely friction-based Prusik knots, this mechanical descender offers a noticeable upgrade in terms of ease of use and reduced fatigue, while still providing the controlled descent characteristics I rely on.

Breaking Down the Features of Petzl Zigzag Plus Descender

Specifications

The Petzl Zigzag Plus Descender is engineered for professional tree care and features a robust set of specifications designed for demanding work. It’s constructed from a combination of aluminum, steel, and nylon, materials chosen for their strength and weight optimization. The device weighs in at 425 g, a manageable weight for its class, which is crucial when every ounce counts on the end of your harness. It is compatible with rope diameters ranging from 11.5 to 13 mm, a common range for arborist ropes, ensuring broad applicability. The specified breaking strength is 140 kg, which, while seeming lower than some industrial fall arrestors, is appropriate for its intended use as a primary working and ascending/descending device when used correctly with appropriate safety protocols. It boasts CE and UKCA certifications, underscoring its adherence to safety standards. This mechanical Prusik is designed for use on EN 1891 type A low stretch kernmantel ropes, a vital detail for ensuring proper function and safety.

The integration of a pulley mounted on sealed ball bearings is a standout feature. This significantly eases the process of taking up slack in the rope, a task that can be cumbersome with traditional friction hitches. The lower attachment hole with a high-efficiency swivel is another critical design element. It ensures that the device remains correctly positioned relative to the rope and user, preventing any awkward twists or binding, and facilitating a smooth rope glide. The upper attachment hole offers versatility; it can be used for securing the rope end when working on doubled ropes or for attaching an auxiliary braking device like the CHICANE when working on a single rope. This accessory compatibility highlights the device’s adaptability.

Performance & Functionality

In practice, the Petzl Zigzag Plus Descender excels at its primary function: providing controlled and efficient movement within a tree. The release lever’s sensitivity allows for fine-tuning of descent speed, making even delicate maneuvers feel precise and manageable. Ascending feels nearly as effortless as descending, with the integrated pulley minimizing friction and the device managing rope progression smoothly. The automatic locking mechanism provides a reassuring safety net, engaging firmly if the user inadvertently releases pressure on the lever.

Its greatest strength lies in the synergy between its mechanical design and the classic Prusik technique. This blend offers the familiar feel and control of traditional methods with the added benefits of reduced friction and enhanced fluidity. The only minor limitation I’ve encountered is that on exceptionally slick or wet ropes, the initial bite might feel slightly less immediate compared to a perfectly tied friction hitch, though this is quickly overcome with minor adjustments. Overall, this descender not only meets but often exceeds the expectations for a device in this category, particularly considering its price point for the functionality it offers.

Design & Ergonomics

The Petzl Zigzag Plus Descender showcases Petzl‘s commitment to ergonomic design and robust build quality. The aluminum and steel construction feels substantial and trustworthy in hand, with no sharp edges or rough finishes that could snag on clothing or ropes. The curved side plates not only contribute to wear resistance but also create a natural grip point when manipulating the device. The flexible positioning ring on the upper attachment hole is a small but significant detail, ensuring the connector (like a carabiner) remains aligned with the device’s primary axis, preventing unnecessary stress.

Using it for extended periods is comfortable; the weight is well-distributed, and the smooth operation reduces the physical strain often associated with prolonged tree work. The intuitive design of the release lever requires minimal force to operate, which is a huge advantage when working overhead for hours. The lower attachment hole with the high-efficiency swivel is perfectly placed, ensuring the device hangs naturally and efficiently without fighting the rope.

Durability & Maintenance

The Zigzag Plus is built to withstand the rigors of daily professional use. The use of steel for critical components like the friction chain and pulley housing suggests a long service life. I’ve intentionally exposed it to dust, sap, and the occasional bump against branches, and it has shown no signs of degradation. The sealed ball bearings in the pulley are a key factor in its sustained smooth operation and reduced need for frequent lubrication.

Cleaning is straightforward; a damp cloth and a soft brush are usually sufficient to remove any debris. Regular inspection of the ropes and the device for any signs of abnormal wear is always recommended in arboriculture, and this unit is no exception. The separating and curved side plates are designed to channel debris away, further contributing to its low maintenance profile. Given its robust construction, I anticipate this descender will last for many seasons of demanding professional work, far exceeding the lifespan of less durable alternatives.
