f. WARNING: MKD U-Brackets are for suspension of loudspeakers only. Suspension of
persons is prohibited.
3. Installation of the MKD Series U-Bracket to a mounting surface
a. Test fit an MKD Series U-Bracket on an MKD Series Loudspeaker to confirm the correct
angle, loudspeaker and u-bracket orientation before installing the U-bracket to the
mounting surface.
b. The MKD Series Loudspeaker may have weather-protected fiberglass shell which
increases the size of the loudspeaker. There are multiple sized rubber washers (E and F)
included with the MKD Series U-Bracket to accommodate
the larger loudspeaker size. Select the rubber washer to
best fill the gap between the loudspeaker and u-bracket
for use equally on both sides of the loudspeaker.
c. Configurations - Depending on mounting option used, the
MKD Series U-Bracket may be installed horizontal (back
and arms are level/parallel to the ground) or downward
(back and arms are plumb/perpendicular to the ground).
Any other configuration is not an EAW-approved
configuration and may result in damage, injury, or death.
Downward configuration

i. Note, the outermost mounting point “A” is
designed as an open slot to allow for easy
locating of an MKD Series Loudspeaker and
loosely pre-installed hardware. If using the
slotted mounting point, the MKD Series U-
Bracket must be installed oriented with the slot
angled upward, opposing the ground.
d. Level - The back channel of the MKD Series U-Bracket must be level when installed to the
mounting surface and before installing an MKD Series Loudspeaker to the U-Bracket.
e. Mounting options
NOTE: It is recommended that you consult a building professional for the proper mounting hardware
before mounting the bracket. Due to various construction methods and materials, the hardware for
securing the bracket to the mounting surface is not supplied. It is required that the use of hardware
locking methods, not limited to lock washers, thread-locker, or nylon-retention feature, be applied
when securing the u-bracket to the mounting surface or structure.
The MKD Series U-Bracket has three mounting options:
i. Four sets of slots for user supplied M6 or 1/4in hardware.
1. These slots are spaced to align for standard stud spacing and allow for
slight variations from standard stud spacing.
2. If installing the MKD Series U-Bracket by these slots, one slot in each of
the four sets must be secured, for a total of 4 slots secured (one slot
secured in each of the four quarters of the back channel).
3. When installing the MKD Series U-Bracket using the slots, the MKD Series
U-Bracket may be installed horizontal (back and arms are level/parallel to
the ground) or downward (back and arms are plumb/perpendicular to
the ground).
ii. Two outer Ø9/16in (Ø14.3mm) holes for user supplied M12 or 1/2in hardware.
1. These outer holes are spaced to align with holes in common structural
channel.
2. If installing the MKD Series U-Bracket by the outer holes, both holes must
be secured.
3. When installing the MKD Series U-Bracket using the outer holes, the MKD
Series U-Bracket may only be installed downward (back and arms are
plumb/perpendicular to the ground).
iii. Two inner Ø7/8in (Ø22.5mm) holes for user supplied hardware.
Horizontal configuration

1. These inner holes are spaced to align with the input section of an MKD
Series Loudspeaker. The two inner holes may be used as a wiring
passthrough in a non-structural, non-load-bearing manner with a 1/2in
(M16) conduit adapter.
2. The two inner holes may be used to structurally install the MKD Series U-
Bracket to a mounting surface using load bearing hardware; both holes
must be secured.
3. When structurally installing the MKD Series U-Bracket using the inner
holes, the MKD Series U-Bracket may only be installed downward (back
and arms are plumb/perpendicular to the ground).
4. Installation of an MKD Series Loudspeaker to the MKD Series U-Bracket.
a. Choosing an MKD Series Loudspeaker configuration
i. Each MKD Series U-Bracket has several MKD Series Loudspeaker mounting and
angle lock options.
ii. Mounting points are indicated below by a letter. The varying mounting points
offer different distance settings to the MKD Series Loudspeaker from the
mounting surface. The varying mounting points also offer different angle lock
settings. The selected mounting point is always connected to the MKD Series
Loudspeaker using the centermost M10 screw location on the top and bottom of
the MKD Series Loudspeaker.
1. Note, the outermost mounting point “A” is designed as an open slot to
allow for easy locating of an MKD Series Loudspeaker and loosely pre-
installed hardware. If using the slotted mounting point, the MKD Series
Rubber Washer (E/F)

B
Flat Washer (C)
Locking Washer (D)
Note: Locking washer is first on bolt, then flat washer

U-Bracket must be installed oriented with the slot angled upward,
opposing the ground.
iii. Angle lock points are indicated below by a number. Use of the angle lock points
is optional. The angle lock points are used for locking the MKD Series
Loudspeaker at a specific pre-determined angle.
1. If an Angle lock point is not used, the loudspeaker may secure the
loudspeaker at any angle by torqueing the mounting point hardware.
2. Note, there is an additional M10 screw in the bottom of each MKD Series
loudspeaker. This one location allows for additional angle lock settings
when using the MKD Series U-Bracket.
iv. The mounting points offer the following lock angles when used in conjunction
with the angle lock points. These angles are measured from perpendicular to the
mounting surface. For a wall-mount configuration, 0° is aiming directly away from
the mounting surface. For a ceiling-mount configuration, 0° is aiming directly
downward.
