Carvin Audio 3900PB is a dedicated pull-back bracket designed to provide a secure attachment point for adjusting the aiming angle of TRx3900F and TRx3903 column arrays. Ideal for suspended installations, it allows installers to “pull back” the column to achieve precise downward tilt and optimized audience coverage.
The Carvin Audio 3900PB bracket enhances installation flexibility by adding a dedicated pull-back connection point to the TRx3900F or TRx3903 column array. In flown or suspended configurations, proper downward angle control is critical for maintaining intelligibility and consistent coverage. The 3900PB allows attachment of rated hardware or safety steel cable (not included) to achieve accurate vertical aiming.
The bracket features two 11.7mm mounting holes for secure attachment to the column array enclosure and a 20.2mm mounting hole designed for connecting pull-back hardware. This configuration supports stable and predictable angle control in theaters, houses of worship, performance venues, and other permanent installation environments.
Installation hardware shown in promotional images is not included and should be sourced separately from a qualified hardware supplier. The 3900PB is engineered for professional installation use and integrates cleanly with compatible TRC column systems.
