Door stopper may be made of wood but it is strong as any metal object. You get a lot hold on the door and the door stays ajar while you are at work. It saves you the time and energy put in keeping doors in their place. It has a firm stopper which is attached to an elongated tail that fixes well. The finish of the wood is marvellous and can keep going for many years. It is supplied in single piece with a 2 year warranty.
