Pro-Line box trailers: frequently asked questions
What does "wheels under box" mean?
The wheels sit underneath the deck, so all four sides can open and remove completely. That gives better control, a lower loading height and loading from any side.
Can these trailers convert to flatbeds?
Yes. The aluminium sides and corner posts remove without tools, instantly converting the box trailer into a flatbed for oversized loads.
What do P2, P3, P4, X5 and X6 mean?
The model code shows deck length and ATM. P2 is about 2.6m, P3 about 3.2m, P4 and X4 about 4.2m, X5 about 5.2m and X6 about 6.2m.
Do they need electric brakes?
No. Pro-Line trailers use Knott mechanical overrun brakes that are RVS/ADR compliant, so no electric brake controller is needed.
What payloads are available?
From about 570kg on light models up to 2,915kg on the 3521 P3, depending on model and configuration.
What do I need to tow one?
1,350kg ATM models suit most vehicles and 2,000kg models suit mid-size vehicles. The 3,000kg and 3,500kg ATM models need a ute, 4WD or commercial vehicle rated to tow 3,500kg.
How do the lashing points work?
Integrated fasteners run through the body and foldaway lashing rings sit inside the box, giving multiple tie-down points that do not protrude when not in use.
