HOWEVER....I was concerned with the road impact literally driving off the glued and screwed halo so I measured up 4 1/4" on the wall and installed a 1x4 cleat the length of the wall to help carry the impact load. With the floor supporting the cleat and the cleat carrying the wall it took a great deal of the strain off of the halo 2x4 edge.
It also made assembly easier as it is hard for one person to hold a 10 foot wall in place and fasten it at the same time. The cleat offered a rest for the wall and assured it would be square and level.
