Home of the Original TREG Poly Block Coupling (BEWARE OF NON APPROVED COPIES !!!)

Back in 1947, Gordon J Tregoning started making trailers. It wasn’t long after this that he recognised a problem with trailer products on the market:  “they weren’t suited to the Australian terrain customers were driving on”.

His solution? Gordon pioneered the original TREG Poly Block Coupling to make towing easier. With safety a key factor, Gordon designed a unique style coupling suitable for the roughest of Australian roads, for all types of vehicles.

The result? A far superior coupling compared to regular ball couplings that are more likely to eject.
