I recently completed a custom design and build for a local portable church. The request was for a portable wall that could be loaded, unloaded, and constructed by a single individual. After much designing I finally devised a leg locking system that would allow the legs to be fully removed and for easy transport but that would also provide plenty of structural support when locked into place.
As a bonus I added handles wheels and side locking mechanisms to fasten all four panels together. Below are some pictures! Enjoy!
