The doorway is one of many gaming inflatables that when combined with other doors, windows and walls forms an "instant" maze.
You can carabin them together with other doors, windows or walls to form a mini-town. See below for an image of the clip locations.
These gaming inflatables are able to be used either indoors or outdoors.
Each doorway has tie down-points in the corners, as well as midway along its sides, and across the bottom.
These gaming inflatables are a high wall with a 2m high doorway, essential for access to a building.
