Metreel publishes a primer on cable drag chains covering alternative names, heavy-duty applications and three sizing parameters that drive premature failure. [S1]
Specifying engineers routinely under-size the inner cavity or pick a chain radius below the cable's own minimum bend, and either mistake shows up as insulation wear or conductor break well before the rated cycle count. The article frames sizing around three measurements (inner height and width, bend radius, travel length) and a 60 to 70 percent fill target, which is the kind of pass/fail rule that belongs on a drawing notes callout rather than buried in a vendor submittal.

What Metreel published
The page titled 'What Are Drag Chains & Why Are They Used?' was published on 2026-07-29 by Metreel, with a header date of 18 Aug 2026. It is written as a primer rather than a product release, covering what drag chains do, alternative names, benefits, heavy-duty variants, and how to choose the right size. The tone is explanatory and aimed at buyers new to cable management, not at a specific product launch. [S1]
Numbers, names and definitions given
The article lists five alternative names for the product: cable carriers, cable chains, cable drag chains, cable track and energy trains. It defines heavy duty cable drag chains as an industrial cable management system made up of a series of interlinked steel or reinforced plastic links that form a self-supporting channel. For sizing it specifies three measurements: inner height and width, bend radius and travel length, and gives a target fill ratio of around 60 to 70 percent. It also gives a common minimum bend radius range of around 28mm up to 100mm or more, and states that the bend radius of the chain should always be checked against the minimum bend radius specified by the cable manufacturer. The benefits list names eight points: built to last, extends the lifespan of cables, increased safety for employees, reduced downtime, reduced costs, suitable for a wide variety of industries, steel drag chains can carry electricity, gases and fluids simultaneously, and various designs available.

What it means for cable drag chain specification
For specifying engineers the useful content is the heavy-duty framing and the sizing checklist. The article positions steel construction as the requirement for high dynamic loads, long travel distances, fast cycle speeds, or exposure to metal swarf, coolants, high temperatures or heavy impact, and lists overhead cranes, gantry systems, large CNC machine tools, automated press lines, steel mill equipment and port handling machinery as typical applications. The 60 to 70 percent fill rule is the kind of value a specifier can lift directly into a cable carrier schedule, and the bend radius range gives a realistic envelope for early layout work. The page is light on standards, test methods or cycle life figures, so any quantitative claim used in a submittal should be cross-checked against the chain maker's datasheet. [S1]
How to verify at the source
The primary source is the Metreel page at the source URL above. Reviewers should read the full 'How To Choose The Right Size Drag Chain' section in situ, since the body text supplied here on travel length stops mid-sentence and any guidance on pitch, link design and material selection is not fully captured. Any chain model, steel grade, temperature rating or cycle life number used downstream of this primer needs to come from the chain manufacturer's own catalogue rather than from this overview. [S1]
