Product information & specifications
DMM Tendon Knee Ascender Lift System
The DMM Tendon is a clever, low-profile knee ascender lift system designed to improve rope ascent efficiency while keeping your setup clean, compact and unobtrusive. Built to provide a tidy and effective solution for lifting knee ascenders, the DMM Tendon helps climbers maintain smoother upward movement with less drag and better system alignment.
At the heart of the system is a long length of high-performance shock cord routed around the full circumference of the climber’s waist. This design gives the DMM Tendon a greater range of elongation and more consistent tension as it stretches, helping the knee ascender lift more efficiently throughout the climbing cycle. When not in use, the system fully retracts neatly inside, helping keep the harness setup clean and uncluttered.
Designed to integrate neatly with DMM Kinisi harnesses, the DMM Tendon is a highly refined rope ascent accessory for arborists who want a more efficient and better organised climbing system.
Key Features
- Designed to lift knee ascenders during rope ascent
- Improves ascending efficiency and system tidiness
- High-performance shock cord routed around the waist for improved elongation and tension
- System fully retracts internally when not in use
- Smooth flared tube inlet helps reduce wear and improve performance
- Dyneema mantle elastic improves durability and lifespan
- Tendon Tube Clips designed to fit Kinisi harness attachment holes
- Includes DMM XSRE Swivel Carabiner for compact connection to the knee ascender
- Can be used with a second XSRE Swivel Carabiner for double lifting power and improved alignment
Improves Knee Ascender Efficiency
The DMM Tendon is designed to help the knee ascender return more effectively during each step of the ascent, improving climbing efficiency and reducing unnecessary slack or drag. This makes ascending smoother and helps create a cleaner, more refined rope walking setup.
For climbers who spend long periods ascending SRT systems, this can make a noticeable difference in efficiency and comfort.
Full-Waist Shock Cord Routing for Better Performance
Unlike shorter elastic lift systems, the DMM Tendon routes its shock cord around the full circumference of the waist. This increases the total available stretch range and helps maintain more consistent lifting tension throughout the movement cycle.
The result is a more even and efficient lift action, particularly useful when paired with modern knee ascender systems.
Retracts Cleanly When Not in Use
One of the standout features of the DMM Tendon is how neatly it stores itself when not under load. The system retracts cleanly into its housing, helping reduce snagging, clutter and unnecessary hanging components on the harness.
Built for Durability & Reduced Wear
The system uses a smooth, flared tube inlet and a Dyneema mantle elastic to reduce friction and wear over time. This helps improve overall efficiency while also extending the working life of the system in regular professional use.
Kinisi Harness Compatible
The Tendon Tube Clips are specifically designed to interface with the attachment holes on DMM Kinisi harnesses, making integration clean and secure for climbers already using the Kinisi platform.
Included Connection Hardware
The DMM Tendon includes a DMM XSRE Swivel Carabiner, providing a secure and compact connection point for the knee ascender.
For enhanced performance, the addition of a second XSRE Swivel Carabiner allows both ends of the elastic to be connected, which can:
- Double the lifting power
- Help keep the system better aligned
