Description The Ruff Land™ Kennel Universal Coupler Kit is designed to secure two like-size kennels together, side-by-side, for in your vehicle, home, or business. Ideal for transit van set-ups and clinic settings. Consider door configurations as a side entry kennel will need to face to the outside for a coupler to fit properly. Works on Medium, Intermediate, Large and X-Large kennels. GenII only.
