A: Steve says: Grip bars are commercially available. And as you may know, they are required in commercial projects here in the United States as part of the Americans with Disabilities Act. A grip bar has to be firmly anchored to the substrate in such a way that it can resist 200 pounds per running foot of the grip bar. So you need to lag it into a stud or studs, or in some cases, cover the whole wall with 5/8- to 1-inch plywood and then anchor it into that.
