When installing Meyer Sound loudspeakers, always observe the following precautions:
Use all Meyer Sound products in accordance with local, state, federal, and industry regulations. Owners and users must evaluate the reliability of any rigging or mounting method for their application. Rigging loudspeakers requires trained and experienced professionals.
Use mounting and rigging hardware rated to meet or exceed the suspended weight.
Make sure to attach mounting hardware to the building's structural components (studs or joists), and not just to the wall surface. Verify that the building's structure and the anchors used for the installation will safely support the total weight of the mounted loudspeakers.
Use mounting hardware appropriate for the installation surface.
Tighten bolts securely. Meyer Sound recommends using Loctite® on bolt threads and safety cables.
Inspect mounting and rigging hardware regularly. Immediately replace any worn or damaged components.
Assembly instructions
Orient the rigging bar to maximize up or down tilt.

Secure each rigging bar with two provided fasteners and fully hand-tighten. For longer-term installations, apply thread locker to fastener threads before installation; thread locker not included.

Combine with the MSK-T1 Splay Kit for vertical arrays. See Accessory Datasheet — MSK-T1 Splay Kit.
The 0.87 in (22 mm) suspension holes accept standard 5/8 in shackles. For single-point suspension, the table below lists the resulting loudspeaker angles: negative values indicate downtilt; positive values indicate uptilt.
