Where to get trolley for track system?

[Jaromir Svoboda]

Hi, I'm looking for trolley with hook like in picture on right side but same width like Rockler trolley on left side. It needs to fit inside metal track. Track is 1-5/8" wide, Rockler trolley is nice fit, but expensive. I was hoping to find them cheaper somewhere.
Thanks.

Lots on options on Amazon...search "Unistrut Trolley". ;)

Or search for Kindorf trolley.

Another option would be a threaded spacer and a couple of bearings....
