Using Toggle Bolts or Hollow Wall Anchors
In the case of lath and plaster walls it may not always be desirable tothe fitting where the stud is positioned, also the handyman may wish to attach fittings to thin-surfaced walls faced with or plasterboard, neither of which are solid enough to take . In this case fitments may be attached by using a toggle. There are two main types of toggles, which are both illustrated below. The toggle illustrated (a) is a ‘spring’ toggle; (b) is a ‘gravity’ toggle.
The function of both types is similar. A hole is drilled in the required position and the toggle is inserted. The spring toggle automatically opens inside the wall covering by force of the spring under the two wings. The single wing of the gravity toggle, as its name implies, opens automatically inside the wall by force of gravity. Both types of toggle have a threaded section and a bolt. The fitment is secured to the wall surface by turning the bolt with a screwdriver. It will, of course, be appreciated that once either type of toggle is inserted in the wall surface, it becomes a fixture and cannot be withdrawn, but should it be necessary, at any later date, to remove the toggle, this may be done by enlarging the entry hole and pushing the head of the toggle through the hole so that it drops down inside the wall surface.
When there are a series of fittings to be affixed to a wall, as in the case of a set of shelves, the easiest way to secure them is to fix a batten, or battens, to the wall by means of screws driven into wall-plugs, or into the studs, or the battens may be secured with toggles. The fittings are then screwed to the battens.
