Chief CMS-0305 3-5' Speed Connect Adjustable Extension Columns

The Chief CMS0305 Speed-Connect Adjustable Extension Column is a professional ceiling-mount extension designed to position projectors and compatible display equipment at the desired installation height. The column provides an adjustable range from 36 to 60 inches (91.4 to 152.4 cm), allowing installers to fine-tune equipment placement in one-inch increments without disassembling the column. Its notched adjustment design simplifies height changes while maintaining a secure connection. The CMS0305 uses a 1.5-inch NPT threaded connection on both ends and is designed for use with Chief ceiling plates and other compatible 1.5-inch NPT accessories.

The column also incorporates flow-through cable management with a cable exit port, helping route installation cables through the column while maintaining a clean setup. A set screw provides additional rigidity after adjustment. Chief specifies a 500 lb (226.8 kg) maximum load capacity, making the CMS0305 suitable for substantial professional AV installations. The column is constructed from aluminum, has a black finish, and carries TÜV and UL certifications. Its listed dimensions are 2.3 x 2.3 x 60 inches, with a product weight of approximately 7 lb.
