Frequently Asked Questions - CHCMS115 Chief

What is the weight capacity of the Chief CHCMS115 ceiling plate?

The CHCMS115 has a maximum weight capacity of 500 lb (227 kg). It is the installer's responsibility to ensure the combined weight of all attached components does not exceed this limit.

What tools are required for installation?

You will need a 9/16" socket wrench, a pipe wrench, a drill with a 1/4" bit, a hex key (included), and a pencil for marking. Additional common tools like a level may also be helpful.

Can this mount be used on concrete ceilings?

No, the CHCMS115 is specifically designed for mounting to 2" x 4" wood stud joists. For concrete or other structures, an alternative mounting solution is required. Always ensure the structure can support five times the equipment weight.

What type of extension column is compatible?

The ceiling plate accepts a 1-1/2" NPT or NPSM threaded extension column meeting ANSI/ASME B1.20.1 (Schedule 40, minimum 0.154" wall thickness, aluminum ASTM B221). Ensure at least four threads are engaged when installing.

How do I ensure proper thread engagement?

When installing the extension column into the ceiling plate's threaded collar, tighten until a minimum of four threads are fully engaged. Then secure the column using the included set screw (B) or security set screw (C) by tightening firmly against the column.

Are all necessary fasteners included?

The kit includes the ceiling plate, set screws, security set screw, hex key, and four 3/8" flat washers. However, you must provide two 3/8" x 2-1/2" lag screws (Grade 2 minimum) to attach the plate to the wood joists.

What safety precautions should I take during installation?

Always read and follow all instructions. Use adequate structural support — the structure must hold five times the combined weight of all equipment. Wear safety glasses, ensure the ceiling can bear the load, and never exceed the 500 lb weight capacity. Use the product only for its intended purpose.

Can this mount be used outdoors?

No, the CHCMS115 is designed for indoor use only. Do not install outdoors or in environments where moisture or extreme temperatures could affect safety.

How do I secure the extension column to the plate?

After threading the column into the collar, use the provided hex key (D) to install either the standard set screw (B) or the optional security set screw (C) into the threaded hole on the plate. Tighten firmly against the column to lock it in place.

How do I route cables through the mount?

The ceiling plate features an integrated cable channel. Route cables through this channel before tightening the lag screws. Also, cables can be routed through the extension column for a clean installation.
