Gravity Bracket Installation Instructions
STEP 1
Determine mounting location of bracket.
A) If a valance has been provided, the bracket base must be
mounted below the valance (See Figure 1-A).

IMPORTANT:
When installing Chase Gravity Brackets, make sure that the
dimensions from the top of the bracket to the header is 2”.
Install shim washers between the lower bracket and the wall
jamb if necessary to ensure the bracket is parallel to the
header.
After installing doors, check to see that the door hangs
square in the opening. If the door panel sags, install
additional shims under the lower portion of the hinge until
the panel is square in the opening. 4 shim washers are
provided with each hinge. If additional shims are required,
use 3/8” flat washers as needed.

B) If the bracket pocket on door has been lowered, then the base
of the bracket must also be lowered the same distance (See
Figure 1-B). Example: If the bracket pocket has been lowered 2”,
then the bracket must be mounted an equal distance down from
the header (See Figure 1-B).

Chase Gravity Brackets are designed to be mounted in the center
of the door frame.
Openings with door frames wider than 16”, or applications where
the brackets will be mounted more than 8” from one side of the
frame will require lowered bracket pockets or valances, refer to
Figures 1 A & B.
Once the location of the bracket has been determined, hold the
bracket base firmly against the jamb and mark one of the top
mounting holes.
Drill and Tap, or Lag securely to the jamb using the hardware
provided.
Move the base of the bracket until the bracket arms are in a
straight line at the center and mark the remaining holes.

STEP 2

holes.
Verify that the frame is Plumb & Square. If not, it may be
necessary to place shims between the base of the bracket and
the jamb, (See Figure 2).
Replace bracket and securely fasten to door jambs.
