WARNING

Failure to use a pre-set depth drill could result in serious injury

or death.

Note: It is preferred that the brackets are screwed directly

into a stud where available. However, drywall anchors

can be utilized when studs are absent at bracket

locations. It is the responsibility of the installing

contractor to provide the appropriate fasteners and

anchors to ensure that the unit is secured properly.
