The Straight Stabilizer is a great accessory when used to connect two panels at the top of your whelping/play pen. Pens come with straight stabilizers for top of panels, but not for the bottom against the floor. This is adequate for smaller breeds and smaller litters. Add additional straight stabilizers for larger litters or medium to large breeds.
The Stabilizer is made out of heavy duty industrial strength PVC. Dishwasher safe.
