This page gathers the trailers of the Finnish brand Tk Trailer that the register could not assign to a named range. These are O2-class car trailers with a gross weight up to 3.5 tonnes, as listed in the Finnish vehicle register Traficom. The BT and BTB type codes carry an attached number that mostly gives the gross weight in kilograms, visible on Bt 850, BT 1500, BT 2700 and BTB3000-2.

The register lists here 21 versions with unladen weights from 210 to 710 kg, gross weights from 850 to 3,000 kg, lengths from 5,745 to 8,800 mm and widths from 1,760 to 2,300 mm.

Tk Trailer covers, with models from 850 to 3,000 kg gross weight, the medium segment of the Finnish trailer market, in which the BT and BTB ranges serve as transport and tandem trailers for trade and agriculture. The continuous BT numbering helps buyers match models with comparable payload across several model years.

On a used Tk Trailer trailer, the condition of the overrun brake, rust on the frame and side panels and the tightness of the floor panels count, and on the BTB tandem versions also wheel bearings and brake linings; spare parts are available through Finnish trailer dealers. A valid roadworthiness inspection date and the condition of the coupling head and hitch also belong to the purchase check. Regular greasing of the coupling head also extends its service life.
