With the Zippi Tunnel there are no limits to the size or shape of system that you can build so you can let your imagination - and your pet - run wild!

The Zippi door frames - when used with a straight connector - allow you to connect the Zippi tunnel to a run, hutch or playpen. An optional 'lock-out' door is available to add to the door frame which allows you to safely contain your pets within a run.

The diameter of the hole is 168mm and the door frame itself measures 253mm x 313mm.
