The structure has the important feature of closing itself and being mobile. The operation of the removable ramp is very easy and practical: it is positioned near the steps only at the time of use, otherwise you can store in a garage/ under stairs/ storage room, to always leave the entrance free.
The structure of the deck ramp consists of a landing parallel to the ground and two wings, one on the right and one on the left, which rest respectively on the last step and on the ground. Opening both wings of the ramp gives a sloping plane thanks to which it is possible to overcome the difference in height.
