Omavalmiste – self-built light trailers just over 750 kg (class O2) from the Finnish vehicle register: single-axle units with overrun brake, model names as load-bed size in centimetres or metres
Omavalmiste is Finnish for “self-made” – the entry of the registration authority Traficom for trailers that private people, farmers or workshops built themselves and registered after a registration inspection (rekisteröintikatsastus). This collective page covers the light self-builds whose gross weight lies just above the 750-kilogram limit and which therefore fall into the braked class O2: trailers built like a light trailer but carrying an overrun brake because the builder had 1,000 or 1,300 kilograms of gross weight entered. The model names are the dimensions the inspector noted: width by length of the load bed in centimetres (130X270, 150X400) or metres (1,88X3,01), the gross weight after the slash (/750, /1000), the axle count as 1-AKS for yksiakselinen.

The register lists 330 versions with kerb weights from 110 to 1,050 kg, gross weights from 755 to 3,500 kg, lengths from 2,200 to 7,350 mm and widths from 1,040 to 2,500 mm.
In Finland the braked single-axle trailer is the trailer of summer cottages and small businesses – for boats, firewood, building materials and snowmobiles – built from series axles and overrun couplings from trade suppliers; the inspection station approves braking performance, lighting, coupling and dimensions.
Anyone taking over such a trailer checks registration and inspection date, frame and welds, overrun brake and brake cables, axle, wheel bearings and tyre age, coupling and breakaway cable, lighting; wear parts are standard items from trailer accessory dealers.
