Securing Large Furnishings
[Credenzas, Filing Cabinets, Bookcases, Shelves]
Regulations require that anything five feet or more in height
must be secured in order to avoid injury to personnel. Items less than five feet are exempt if
the supporting base is 2/3rds of the height.
Ideally these items are anchored to the wall
studs or into the floor. When possible, this is done from inside the piece
using "hi-lo" screws with fender washers.
When the location or construction of the item prohibits this method,
inverted "L" brackets
are used. Aesthetically, either method usually keeps the materials from view.
To further strengthen the resistance to earth tremors, pieces are "ganged" together
from inside using nuts, bolts and large washers. The use of washers is
necessary to prevent the bolt heads
from shearing through thin metal walls of cabinets.
