Description Reviews The Rubber Crate Floor mat has a textured, non-slip surface. Clean up is easy, just rinse down the mat with a garden hose. The mat is 1/2″ thick and is extremely durable for long lasting use. The mat provides a surface for a dog to grip when a car accelerates or makes a sharp turn. This is especially helpful to police K9s while the vehicle is in pursuit. Please note these sizes are specific to ActiveDogs Full Vent Crates.
