So I bought a used snowmobile trailer that has two tracks for sliding tie-downs in. Track looks much like a Versa-Track. The trailer came with two sliding loop tie downs but no ski tie downs. Nobody locally seems to sell Versa-track ski tie downs and you can't seem to buy these online anywhere. Are there any other options? In looking at the Loadrite webpage it appears that their sled trailers have a similar track and a "more basic" ski tie down that slides in the track.

Never thought it'd be this hard to find a "track" ski tie down bar.

Contact you local Triton dealer.
The Toronto area Triton dealer had all the bits and pieces for sale at the recent Toronto Snowmobile Show.
