Not cheap: Nuts

Not cheap, you can get 50 pieces cheaper from China. I was in a hurry to finish the project, otherwise they would not have been ordered.

Pros
  • Good product for the price
Cons
  • No

4040 too small

4040 T-nuts are not deep enough, they just hang in the groove. They are not deep enough for the ball to reach the back of the T-slot and hold it in place.

Pros
  • Satisfied so far
Cons
  • High price

3030 series sliding blocks fit Ikea Vidga runners

These 3030 series sliding blocks fit perfectly into the smaller slot of the Ikea Vidga drapery/curtain rails. I will be using these with M6 thumbscrews as a workaround instead of plastic inserts to connect to the wall mounts.

Pros
  • Lots of positive emotions
Cons
  • Don't know

PLEASE READ FIRST: Strong but too small for P2020. just slips out.

This is a great concept and I'm sure there is an extruded aluminum track somewhere in the world that they fit perfectly into, but none of mine seem to hook the ball. It just rattles in the rail and falls off where you set it. They work just as well as a regular nut (except for the elastic/solid spring ball).

Pros
  • Easy install
Cons
  • Pretty ok
