The housing has a hollow interior with a hinged access door which folds down to form a footrest, the door having support feet to lift it from the floor. The housing itself is supported on metal or plastics rollers so that it can be readily pushed along the floor, with a handle attached to the top to allow it to be carried.</p> |
