Product Overview
The Chief CMA290 is a 10-pack of cable locks that provides a flexible hanging and securing solution for AV equipment. It gives integrators a fast way to suspend or anchor components using wire rope with a one-way clamp mechanism. The locks install with a quick-release lever and accept 0.13" (3 mm) or 0.19" (5 mm) diameter wire rope. It is intended for commercial AV installations such as ceiling-mounted equipment and rack-mount support.
Product Description

The CMA290 supplies ten cable locks that let installers hang or secure a range of equipment with flexible wire rope. Each lock uses a one-way clamp mechanism that holds the rope under load and a quick-release lever that makes installation and adjustment fast. The locks accept wire rope in 0.13" (3 mm) or 0.19" (5 mm) diameters, covering light to moderate suspension needs. Because the solution is rope-based rather than rigid, it adapts to various equipment shapes and mounting points where a fixed bracket would not fit. It is a practical accessory for ceiling-suspended AV components, safety tethering, and commercial-grade installations where flexible hanging is required. As a Chief commercial-grade accessory, professional installation is recommended. Browse additional cable management and mounting accessories in the Chief collection at Creation Networks.
