Hi Don
Here's a link to one that Bob & Rick made also they made one that was a hook type but I could not find that one on the list.
It was neat one with interlocking tabs that hooked all 4 sides into one planter.
But it would work also for a Triangular planter.

FOUND IT Don
it's called a Puzzle Planter
It would be a bit ticky to make in a Triangular planter but it can be done.
