16mm Nylon Webbing: A Balance of Strength and Durability
The GM CLIMBING Safe Chain employs 16mm tubular nylon webbing, providing a substantial 22kN breaking strength for all loops. This width is chosen to offer a robust feel and durability against abrasion, which is crucial for a personal anchor system frequently used in varied outdoor environments. While lighter materials exist, 16mm nylon strikes a practical balance for comfort, load distribution, and longevity in climbing applications.
Independent Loop Strength: Critical for PAS Safety
A key advantage highlighted by the GM CLIMBING Safe Chain's design is the 22kN strength rating for each individual loop. Unlike some older daisy chain designs, where only the main tether might be rated, this PAS ensures every loop offers full strength. This is vital for climbers needing precise length adjustments at anchors, providing consistent safety margins regardless of which loop is clipped.
Nylon's Abrasion Resistance in Climbing Tethers
The use of nylon in the GM CLIMBING Safe Chain's 16mm webbing offers inherent advantages for durability in climbing scenarios. Nylon excels in resisting abrasion from rock surfaces and gear, a common wear factor for personal anchor systems. While Dyneema offers higher tensile strength, nylon's greater elasticity and better performance when subjected to impacts and friction make it a reliable material choice for this application.
Expert answers based on real user experience
Unlike many traditional daisy chains where only the main attachment point is rated to high loads, GM CLIMBING's Safe Chain ensures each individual loop, as well as successive adjacent loops, is independently rated to 22kN. This is critical for personal anchor systems, where clipping into any loop for precise positioning is common. The entire sling also meets CE and UIAA certifications, providing a standardized safety benchmark for critical load-bearing applications during climbing transitions. This independent loop strength is a key differentiator for secure anchor management.
The integrated half-twist on the long end loop of the GM CLIMBING Safe Chain is designed for a cleaner girth hitch knot. This specific construction allows the hitch to sit flatter against your harness belay loop or tie-in points, reducing potential snagging and bulk. It also prevents the webbing from twisting on itself during attachment, maintaining a more streamlined profile. This design ensures a secure and low-profile connection without compromising the webbing's structural integrity when used as a personal anchor system.
While the GM CLIMBING Safe Chain uses 16mm nylon tubular webbing with a 22kN rating, precise lifespan figures for sewn loops under varied dynamic and static loading conditions are not typically provided. Nylon webbing can degrade over time due to UV exposure, chemical contact, and abrasion, especially at the sewn junctions. Professional assessment suggests that while the double-layer stitching enhances durability, regular inspection for fraying, degradation of the nylon fibers, or any compromise in the stitching is crucial. Climbers should consider a replacement every 5 years or sooner if signs of wear are visible, especially with consistent use in abrasive environments like granite or sandstone.

The CE (Conformité Européenne) and UIAA (International Climbing and Mountaineering Federation) certifications on the GM CLIMBING Safe Chain PAS confirm it meets stringent international safety standards for climbing equipment. Specifically, the 22kN breaking strength rating across all loops signifies its capability to withstand forces encountered in critical fall arrest scenarios or during prolonged suspension. These certifications provide assurance that the product has undergone rigorous testing for material integrity, load-bearing capacity, and overall safety performance, key for personal anchor systems in climbing and construction applications.
The 97cm (38-inch) length of the GM CLIMBING Safe Chain offers significant adjustability for personal anchor systems. Its multiple interlocked loops allow climbers to precisely shorten the tether by clipping into successive loops, accommodating anchor points that are close or far. This rapid length adjustment capability, without needing to tie knots that reduce strength, is particularly useful when setting up a rappel or managing gear at a hanging stance, providing a versatile range for different climbing scenarios.
