I'm trying to find a source for this type of plastic rack gear:

enter image description here

This image came from this youtube video.

I can find short pieces of straight rack gear on ebay, but nothing like this.

It appears to be a vinyl/plastic type material, has 90-degree mounting flange, and is toothed on both sides.

Any information would be appreciated!

  • $\begingroup$ @sunny it's a similar application : moving a hollow core door (45lbs) on roller track. Yes i have looked at belts but was interested in this rigid type. Thx $\endgroup$ Apr 22 '19 at 18:24
