Title: Mastering Tree Climbing with the Unicender Device – The Ultimate Versatile Tool for Arborists

When it comes to climbing innovation in the arborist world, few tools have sparked as much interest and admiration as the Unicender Device. Known for its simplicity, versatility, and durability, the Unicender is a favorite among seasoned tree climbers and rope access professionals looking to streamline their climbing systems without sacrificing safety or performance.

What is the Unicender?

The Unicender is a mechanical rope-climbing device designed to function on both Single Rope Technique (SRT) and Moving Rope System (MRS) configurations. Created by arborist Morgan Thompson, and manufactured by Rock Exotica, the Unicender stands out as a revolutionary piece of kit because it can be used to ascend, descend, and work-position on the rope—all with a single device.

Key Features

1. Dual Rope Compatibility (SRT & MRS)

One of the Unicender’s most celebrated features is its unmatched compatibility with both SRT and MRS climbing styles. With no need to switch out or modify the system, climbers can transition seamlessly between techniques as needed, making the device ideal for diverse job sites and complex tree structures.

2. Friction-Based Operation

The Unicender uses a unique multi-arm cam system to provide controlled friction on the rope. This system eliminates the need for traditional hitches or knots, reducing rope wear and potential failure points. It engages and disengages smoothly, offering fluid ascents and effortless descents.

3. Tool-Free Adjustment

No tools are required to adjust the Unicender or switch it from SRT to MRS. This makes it field-friendly, saving arborists valuable time during setup and breakdown.

4. Durability

Crafted from anodized aluminum and stainless steel, the Unicender is built to last. Its robust construction handles the demands of daily tree work and resists corrosion in tough outdoor environments.

5. Minimal Rope Wear

Because the Unicender doesn’t rely on a rope-squeezing mechanism like traditional friction hitches, it causes significantly less rope abrasion, preserving the life of your climbing lines.

Benefits for Arborists

• Simplifies gear loadout: Carrying one device for both SRT and MRS reduces clutter and weight.

• Smooth rope handling: Ideal for long climbs or technical work positioning.

• Confidence in safety: Its mechanical locking design offers consistent performance in wet, dirty, or cold conditions.

• Great for advanced climbers: While it has a learning curve, experienced users often find it far superior to traditional hitch systems in efficiency.

Considerations Before Use

While the Unicender is a game-changing tool, it’s not necessarily for beginners. The device has a learning curve and requires proper training to use safely and effectively. It’s essential to:

• Watch detailed tutorials and training videos

• Practice in a controlled environment

• Use compatible ropes (typically 11-13mm)

• Regularly inspect the device for wear and cleanliness

Final Thoughts

The Unicender Device is a true innovation in the world of rope access and arboriculture. For professional climbers looking for a streamlined, multi-functional, and highly efficient rope system, it delivers unmatched performance. Whether ascending to great heights or fine-tuning your position in the canopy, the Unicender gives you the control and reliability needed to take your tree work to the next level.
