Overview

The RectorSeal TRUaire 81914 is a plastic ceiling diffuser with an integrated ceiling box, designed for residential and light commercial spaces. It is offered in 8x8 square 4-way, 6x6 square, and round configurations, combining grille, damper, and box into a single ready-to-install unit. The one-piece design supports fast installation and a clean ceiling finish, even in tight or awkward ceiling spaces.

Fast installation from below

Built for one person to install from below the ceiling, this diffuser is engineered for speed. Features such as quick tear-off bands and swinging clips help secure the assembly in seconds, making the install process straightforward even for less accessible ceilings.

Durability and seal

Made from high-grade polymers, the grille resists breakage, scratching, yellowing, and fading, helping maintain a fresh appearance over time.
