Seeing this structure at a local school yesterday took me back to my public school days when during one gym class the teacher proudly folded this new apparatus out 90 degrees from the wall to reveal various climbing and gymnastic possibilities. I learned to climb a rope on it but really can't remember gym classes using it that much.
This one is only a single bay (two frames), the ones I remember were three.
The vaguely nervous principal declined to fold it out for me to relive my youth and take proper pictures, I don't know why!
I could find no identification or manufacturers label and there is virtually nothing online about what was once a ubiquitous Ontario public school gymnasium fixture.
