The Adjustable Ramp is perfect for pets who need a little help getting through the Pawport door, especially where the exterior of the home may be slightly elevated. Constructed of high-strength steel and powder coated to last many years in harsh conditions, the ramp easily installs (exclusively) to the outside of the Pawport Tunnel & Frame System, and adjusts to the height and length that best suits your home and pet. The included turf floor protects against dirty paws.
