holes are 16 inches apart from their centers.

two ways

Attaching to wall stud

2.

Attaching to wall anchor

Attaching to Wall Stud

:

 This method pro-

vides the strongest hold. Insert mounting
screws through mounting bracket and into
wall studs.

Attaching to Wall Anchor:

 

 This method

allows you to attach mounting bracket to
hollow walls (wall areas between studs) or
to solid walls (concrete or masonry).

Decide which method better suits your needs.
Either method will provide a secure hold for
the mounting bracket.
