We built an L-shaped cage for one of our herds, so it uses two coroplast bases due to the shape. One of our boys is a little hesitant to jump over the "wall" between the two sections, so the ramp gives him an easy way to move from one section to the other. it was a nice, inexpensive fix for this issue. The only negative is that the pigs often stick their head under the ramp and flip it so it folds in half, so we need to check and fix it frequently.
