Sliding Benchtop Organizers

I don't have a lot of room in my workshop, so I need to make the most of the space. I have six of these Pinnacle Benchtop Organizers:

It would be convenient to have them all facing the right way on my shelves, but I decided to turn them sideways and slide them out to save space. I attached sliding drawer rails to them to make this more convenient.

It was a bit tricky to figure out how to do this. The bottom of the organizer looks like this:

I cut up a sheet of hardboard and attached the pieces to the organizer using metal screws.

Then I was able to attach the drawer slides to the piece of wood.

I was worried about the weight when pulling them out, but they seem to be fine. There is a slight bend for some of the heavier organizers, but they are only open for a very short time, so I'm not too worried about it.
