Octagonal 8-panel exercise pen sets up a 63 by 63 in zone for medium pets and stands 30 in high to discourage jumping. Each carbon steel panel measures 30 in tall by 24 in wide and locks into the next with reinforced hinges. A 600D Oxford and Pvc mesh top cover snaps over the frame to block sun debris and pets that try to leap out. Eight ground stakes and 16 tension straps anchor the pen outdoors for picnics or training sessions. The frame folds flat for closets car trunks and travel.
