Installation instruction

MKC Series U-Bracket limits of use

• The MKC Series U-Brackets are designed to suspend each corresponding MKC Series loudspeaker with a design factor designated on its appropriate bracket label or exceed most global suspension regulations. The maximum working load limits of each MKC Series U-Bracket can be located on its appropriately applied label. These values have been confirmed with Finite Element Analysis and destructive testing.
• The weight/mass of each MKC Series U-Bracket is also listed on its appropriately applied label.
• The MKC Series U-Brackets are designed to suspend only one loudspeaker per u-bracket.
• Any geometric or structural modifications to the MKC Series U-Bracket or hardware that are not EAW-approved will void the warranty and may result in damage, injury, or death.
• WARNING: Take care when lifting MKC Series products to avoid harm or damage to the product.
• WARNING: MKC U-Brackets are for the suspension of loudspeakers only. Suspension of persons is prohibited.

Installation of the MKC Series U-Bracket to a mounting surface

• Test fit an MKC Series U-Bracket on an MKC Series Loudspeaker to confirm the correct angle, loudspeaker, and u-bracket orientation before installing the U-bracket to the mounting surface.
• Configurations
  Depending on the mounting option used, the MKC Series U-Bracket may be installed horizontally (back and arms are level/parallel to the ground (figure

1. or vertically (back and arms are plumb/perpendicular to the ground (figure 2)). Any other configuration is not an EAW-approved configuration and may result in damage, injury, or death.
   NOTE: the outermost mounting point “A” is designed as an open slot to allow for easy locating of an MKC Series Loudspeaker and loosely pre-installed hardware. If using the slotted mounting point, the MKC Series U-Bracket must be installed oriented with the slot angled upward as visually shown in Figure 1, opposing the ground.

• Level – The back flange of the MKC Series U-Bracket must be level when installed to the mounting surface for either figure 1 or 2 orientation and before installing an MKC Series Loudspeaker to the U-Bracket.d. Any geometric or structural modifications to the MKC Series U-Bracket or hardware is not EAW-approved will void the warranty and may result in damage, injury, or death.

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 features, be applied when securing the u-bracket to the mounting surface or structure.

One Ø5/8in (Ø15.9mm) hole.

1. This hole can be used as a ceiling pole mount or a wall wire pass-through.
2. If installing the MKC Series U-Bracket by this hole, a secondary safety point is suggested to be secured.

Two inner Ø5/16in (Ø8.5mm) holes.

1. These inner holes are spaced apart from each other in the center and aligned.
2. These two inner holes may be used to install the MKC Series U-Bracket to a mounting surface using load-bearing hardware; both holes must be secured.
