@Amy262 I think you're talking about the 3x1 Loft half way up the 3x2 lowest floor? It's a 3x1 floor zip tied on the back and sides to the walls 5 grid squares up. It was pretty secure since it's the minimum 3 grids wide, but to prevent bowing, I clipped 3 small spring clips from the Loft railing to the ceiling in one spot. Now that I added the small interior ramp to the loft, the ramp itself is so sturdy, it gives some support as well. Another option would be to have the tunnel taller, and support the edge of the loft....
The photo may explain it better. I think everyone should add one! So easy, it creates a nice big built in hidey house, and most importantly- it frees up space for long lap running.
One more tip, I cut the thick perimeter of the grids with a very small hack saw. I used this same saw to miter the corners of the 1/4" slide binder clips I used to finish raw edges. That's how I achieved a nice clean short grid piece for the crucial railings.
