It is important to stop the weight hanging on the wall. This is done by having the ribbed wall bar stand on the floor and a number of brackets on the wall high up (4 pieces), hold it so it cannot tilt out under load. The same goes for brackets just above the floor (2 pieces). What the attachment should be made with depends on what the wall is made of. Of course, concrete is always best, but it can be done with plasterboard, but then there must be a wooden board behind.
