Mounting Kit Chief CMS261 Black Metal Maximum Weight Capacity 226.8 kg

Bolt-on coupler that adds 1.5" NPT threads to a Chief extension column which has been cut to a shorter length. The coupler increases installation height by 2" (51 mm) and is supplied with set screws and bolts to secure the connection. Designed to be used with Chief extension columns and compatible mounting components, it allows truncated columns to accept standard threaded accessories.

Advantages

The coupler provides a reliable method to restore threaded connections on shortened Chief extension columns without replacing the column. Inclusion of set screws and bolts ensures a stable, secure joint. The added 2" (51 mm) of height offers minor adjustment to mounting position while maintaining the structural strength expected from metal mounting hardware.

Suitable for

• Repairing or modifying Chief extension columns cut to a shorter length
• Mounting displays, projectors or AV equipment that require 1.5" NPT threaded connections
• Professional AV installations where a secure, bolted connection is needed

Key specifications

• Thread type added: 1.5" NPT
• Additional height: 2" (51 mm)
• Material: metal (black finish)
• Includes set screws and bolts for securing the coupler
• Compatible with Chief extension columns and related mounting hardware

How to use

Position the bolt-on coupler over the cut end of the Chief extension column so the internal thread aligns with the column. Fasten the coupler in place using the supplied set screws and bolts, tightening to the manufacturer’s recommended torque for a secure fit. Once installed, the new 1.5" NPT threads accept compatible threaded accessories or extensions and the added 2" height provides slight adjustment to the installed equipment position.

Recommendations

Before installation, verify compatibility with your specific Chief column model and ensure all fasteners are tightened to recommended torque values. Use appropriate tools and follow site safety procedures when lifting and installing mounted equipment. For installations near the product’s maximum load capacity, verify the overall mounting system (column, coupler, mount and display) supports the intended weight.
