The core component of the Bak-Rak Swan to Flange adaptor is our patented clam shell.  The clamshell clamps onto the 50 mm towball and is the basis of all our products.

The casting sits over the clamshell and a M12 bolt tightens it all together.   The fabrication is bolted to the casting – this fabrication provides 2 16mm holes on a 90mm centres – this replicates the mounts on a traditional flange-mounted tow bracket.
