ROCK EXOTICA AKIMBO SRT Tree Climbing Device User Manual
Model: AKIMBO SRT | Brand: ROCK EXOTICA
1. Introduction
The ROCK EXOTICA AKIMBO SRT is a high-performance mechanical device designed for professional arborists and tree climbers. It facilitates both Single Rope Technique (SRT/SRS) and Moving Rope System (DdRT/MRS) climbing methods. Its lightweight and compact design, weighing only 261g, allows for efficient and versatile use. The AKIMBO features tool-free friction adjustment, enabling quick adaptation to various rope types and climbing scenarios. This manual provides essential information for the safe and proper operation, maintenance, and care of your AKIMBO device.

2. Safety Information
WARNING: Tree climbing and rope access activities are inherently dangerous and can result in serious injury or death. It is imperative that users receive proper training and understand the risks involved before using this equipment. Always follow local regulations and industry best practices.
- Read and understand this entire manual before use.
- Only use the AKIMBO with ropes approved by ROCK EXOTICA and listed in this manual.
- Regularly inspect the device and rope for wear, damage, or deformation before each use. Discard if any damage is found.
- Ensure all connections are secure and properly engaged.
- Never exceed the stated Total Working Load Limits (TWLL) for the device and rope system.
- The AKIMBO is designed for a single user.
- Seek professional training from a qualified instructor for proper climbing techniques and equipment use.
3. Product Components
The AKIMBO SRT device consists of several interconnected components designed for secure rope management and friction control. Key components include the main body, upper and lower friction cams, and attachment points for carabiners.

4. Setup and Rope Installation
The AKIMBO allows for easy mid-rope attachment and detachment without the need for additional tools. Follow these steps for proper rope installation:
- Open the Device: Hold the AKIMBO and pivot the movable plates to open the rope channel.
- Insert Rope: Carefully feed the climbing rope through the designated path, ensuring it passes over the friction cams as indicated by the device markings.
- Close the Device: Pivot the plates back into their closed position, ensuring the rope is securely captured within the device. Verify that the device is fully closed and locked.
- Attach to Harness: Connect the AKIMBO to your climbing harness using a suitable carabiner, ensuring the carabiner is properly oriented and locked.
- Adjust Friction: Before ascending or descending, adjust the friction settings using the dials on the device. Refer to Section 5 for detailed friction adjustment.

5. Operating Instructions
5.1. Friction Adjustment
The AKIMBO allows for tool-free adjustment of friction to optimize performance based on rope diameter, condition, and user weight. There are two friction adjustment dials, one at the top and one at the bottom of the device.
- Upper Dial (Friction): Adjusts the initial friction on the rope. Settings typically range from A (least friction) to F (most friction).
- Lower Dial (Exotic): Provides fine-tuning of friction, often used to compensate for rope characteristics or specific climbing styles. Settings typically range from 1 to 7.
Experiment with different settings in a controlled environment to find the optimal friction for your specific rope and climbing technique. Always ensure sufficient friction for safe control.

5.2. Ascending (SRT/SRS)
When ascending using the Single Rope Technique, the AKIMBO acts as a self-tending friction device. As you move upwards, the device should smoothly feed rope, and when weighted, it should lock securely. Ensure your friction settings provide adequate hold without excessive drag.
5.3. Descending (DdRT/MRS)
For descending in a Moving Rope System, the AKIMBO allows for controlled descent. Manage your descent speed by adjusting your grip on the free end of the rope and fine-tuning the friction settings as needed. The device should provide a smooth, consistent lower without sudden slips or jerks.
6. Rope Compatibility
The AKIMBO SRT is compatible with specific climbing ropes. Using unapproved ropes can compromise safety and device performance. Always use ropes recommended by ROCK EXOTICA. The following table lists approved ropes and their corresponding Total Working Load Limits (TWLL):
| Total Working Load Limit (TWLL) | Approved Ropes |
|---|---|
| 100 kg | Samson Voyager Cool (11.8mm), Teufelberger XStatic (11.7mm), Yale Poison Ivy / Blue Moon (11.7mm) |
| 130 kg | Cousin Atrax (11.6mm), Sterling Scion (12.5mm), Sterling WorkPro (12.5mm), Sterling HTP (12.5mm), Teufelberger Fly (11.1mm), Teufelberger Drenaline (11.8mm), Yale Scandere (11.7mm) |
7. Maintenance and Inspection
Proper maintenance and regular inspection are crucial for the longevity and safe operation of your AKIMBO device.
- Cleaning: Clean the device with fresh water and a mild soap solution. Rinse thoroughly and allow it to air dry completely before storage. Avoid harsh chemicals.
- Inspection: Before and after each use, perform a thorough visual and tactile inspection of the AKIMBO. Check for:
- Cracks, dents, or deformation in the metal components.
- Excessive wear on the friction cams or rope channels.
- Loose or missing fasteners.
- Proper function of the opening/closing mechanism and friction adjustment dials.
- Storage: Store the AKIMBO in a clean, dry place, away from direct sunlight, extreme temperatures, and corrosive substances.
- Service Life: The service life of the AKIMBO depends on its frequency of use, storage conditions, and exposure to environmental factors. If in doubt about its condition, retire the device.
8. Troubleshooting
If you encounter issues with your AKIMBO, consider the following common troubleshooting steps:
- Device Slipping: If the device slips excessively or does not hold the rope securely:
- Verify that you are using an approved rope type and diameter (refer to Section 6).
- Adjust the friction settings to a higher level using both the upper and lower dials.
- Check the rope for excessive wear, glazing, or contamination that might reduce friction.
- Inspect the friction cams for wear or damage.
- Difficulty Feeding Rope: If the rope is difficult to feed through the device:
- Ensure the rope is correctly installed and not twisted.
- Adjust the friction settings to a lower level.
- Check for any debris or obstruction in the rope path.
- Device Not Closing/Opening Properly: Ensure there is no debris obstructing the pivoting plates. Do not force the mechanism.
If problems persist after troubleshooting, discontinue use and contact ROCK EXOTICA or a qualified service technician.
