This tow bar receiver hitch is designed to fit standard 50mm tow bars with a rating of up to 3,500kg. Ths receiver is compatible with 50mm x 50mm square steel box sections.

Important to note that Couplemate recommends using a solid cast receiver hitch for all off-road couplings (such as the DO35), as hollow receivers with welded tongues may deform in extreme off-road conditions or under shock loading events on highways.

Before purchasing tow bar receivers, it’s important to ensure that your tow bar rating is appropriate for your trailer weight.

A solid 50mm towbar ball mount typically has a Class IV or 4t rating, depending on the grade of the tow bar. If your tow rating is 3.5t, then the tow bar receiver rating should also be 3.5t or lower.

Towbars are subjected to static load testing upon installation, and your tow bar installer will certify it according to Australian Standards.

It’s also important to inspect hitch pins and hitch pin clips for wear and tear at least once a year, as loose clips can fall out due to repetitive removal and re-insertion.

This tow bar receiver is suitable for towing boat trailers, horse floats, caravans, and trailers.
