Truck & Trailer Safety Chain Systems
A runaway trailer of any type or size has the frightening potential to cause death, severe injuries or catastrophic property damage.
The patented Bartlett Bare Knuckle (BK) Safety Chain range is the latest safety innovation from Bartlett designed to reliably stand guard against accidental trailer separation. During trailer coupling separation, the ADR62/02 compliant Bare Knuckle system is designed to immediately take hold and maintain the combination, providing the best opportunity for a safe, controlled, emergency stop.
Compliant Practical Protection
Bare Knuckle is professionally engineered and contoured to closely match the high tensile chain specified in Australian Design Rule 62/02.
Each model has been exhaustively tested in various mounting orientations* to ensure versatility, maximum strength and optimum protection. Component Registration Numbers CRNs, are available to include in vehicle compliance submissions.
Easy to install and use
- Installation and operation are straight-forward.
- Towbar attachments have releasable pins to allow easy and direct chain insertion.
- Trailer attachments have high tensile pins and pinch clips to permanently retain the chains with the trailer.
- No need for extra chain connecting links.

Chain Dog Trailers
Bartlett have called for Dog Trailers to be fitted with safety chains since the 1990s. Their exemption is based on the false belief that emergency trailer braking systems will perform as imagined.
However, Dog Trailers continue to separate with disturbing regularity. Varied braking efficiencies at each wheel of the steering dolly could effectively steer a runaway Dog trailer towards potential catastrophe.
A Complete System
Fleets should operate on the principle that no trailer coupling is infallible, no matter how good their operators or maintenance regimes. Hidden mechanical defects; bad installation, operational or maintenance errors all have the potential to cause sudden malfunction.
Bare Knuckle is a tested and rated safety chain system designed to act as the passive emergency safety backup to the trailer coupling.
Stay Connected – Maintain Control
With new Chain of Responsibility (CoR) laws in place, investigators will look to discover, “what measures could have reasonably been taken to avoid the separation?”
The surest and simplest option available for the best chance of a controlled, safe stop during coupling separation is the ADR62/02 compliant, Bartlett Bare Knuckle safety chain system with a range covering light vehicles right through to the heaviest truck and trailer combinations.
Summarised Legal Requirements
The following guide is designed to assist fleet managers, OH&S officers and authorities to quickly identify non-conformity.
Safety Chains and rated safety chain attachments are mandatory for every rigid drawbar trailer.
Safety Chains remain non-compulsory for hinged drawbar DOG trailers despite this trailer type being clearly conspicuous in accident statistics. The National Standard VSB6 strongly recommends safety chains for all trailers.
Except Road Train
Rated safety chain attachments must be fitted to every towbar regardless of the intended trailer to be towed. A towbar without safety chain attachments does not comply with ADR62.
