Chief CPA353

The Chief CPA353 Floor-to-Ceiling Clamp-Style Plate is a structural mounting accessory designed for installations where the ceiling or wall cannot bear the load of a display system. By clamping to a floor-to-ceiling pole, the plate transfers load to the floor rather than the structure above, opening up display installations in challenging architectural environments. It is compatible with Chief's CPA and CMS extension columns and works with the full range of Fusion ceiling single-display and back-to-back mounts, making it a practical adapter for corporate lobbies, retail floors, and open-plan spaces where conventional ceiling fixings are impractical.

Install Where Ceilings Cannot Bear Load

The CPA353 is built for spaces where the ceiling or wall structure is unable to support the full weight of a display installation — think open-plan office buildings with suspended ceilings, glass atriums, or retail environments with concrete soffits that cannot be drilled. By using a floor-to-ceiling pole as the structural backbone, all load is transferred to the floor rather than the ceiling. The clamp plate grips the pole firmly, keeping the display rigidly positioned without any ceiling penetration. This removes a common project-blocking constraint and allows AV installations to proceed in venues that would otherwise require expensive structural reinforcement work.

Generous Clamp Clearance for Faster Installation

One of the most practical time-savers on this plate is its larger clamp clearance area. When installers cut a pole to length on site, small deviations in cut precision are inevitable. A tight-tolerance clamp demands a near-perfect cut or the clamp will not close properly. The CPA353's wider clearance window accepts a broader range of pipe end conditions, meaning the installer spends less time re-cutting or filing pipe ends and more time completing the job. On multi-pole installations — such as a two-column video wall floor — this adds up to meaningful time savings and fewer frustrated callbacks.

No ceiling fixing needed. Full display stability, floor to ceiling.

Portrait and Landscape Orientation Support

The CPA353 accommodates both portrait and landscape display orientations, giving integrators full flexibility over how content is presented on a pole-mounted screen. Portrait orientation is increasingly common in retail digital signage — particularly for menu boards, wayfinding displays, and narrow-column applications — while landscape suits most corporate and presentation environments. Because the orientation decision does not affect which plate is specified, the same CPA353 can be used across a mixed estate of displays without any hardware changes.

Broad Compatibility Within the Chief Fusion Ecosystem

The CPA353 is designed to integrate directly with Chief's CPA and CMS extension columns, as well as CPAE columns in the EMEA region. Above the plate, it accepts the full range of Fusion ceiling mounts — including single-display and back-to-back configurations — allowing the same head units used in standard ceiling installs to be deployed on floor-to-ceiling poles without additional adapters. For sites with existing Chief infrastructure, this means the CPA353 can extend an installation into a structurally difficult zone while keeping hardware sourcing, spare parts, and service procedures consistent across the whole project.
