Sixteen metal panels is a lot of enclosure - enough to ring a large area of lawn or divide a room in two. This is the 32 in height, sized for small and medium dogs; the same pen is sold at 24 in for puppies and 40 in for larger breeds. Each panel measures 31 in wide, with an 11 x 24 in door and reliable locks on it. Anti-slip footpads protect a floor indoors and stakes hold the run on grass. At this height the set weighs 66 lbs. Black metal throughout, folding down for storage.
