Compliance and Safety

Install the kit only on a structurally suitable trailer drawbar, then confirm chain articulation, chain crossing and clearance through the full towing movement range. The BK20 system uses an 8mm minimum base thickness requirement, so the drawbar substrate must suit the installation.

Use qualified heavy vehicle repair personnel for welding and safety chain attachment work. If a trailer separation incident has loaded the safety chain hardware, replace the affected chain and attachment components before reuse.

Trailer Applications

Workshops fit the Bare Knuckle 20mm trailer chain attachment kit to heavy rigid drawbar trailers and high ATM builds that require rated trailer-side chain retention. It suits new builds, retrofits and fleet standardisation where the matching truck-side attachment and chain set need to work as a system.
