Jbl Professional MTC-SG6/8 Square Grille C328 C277

Product Description

The JBL PROFESSIONAL MTC-SG6/8 is a square replacement grille designed for use with JBL ceiling speaker installations. This accessory provides a clean, finished appearance for speaker cutouts in ceiling tile or drywall applications. It is a direct-fit grille intended to pair with compatible JBL ceiling speakers, maintaining the aesthetic integrity of installed audio systems in commercial and light commercial environments. AV integrators and low-voltage installation technicians are the primary trades working with this component.

The MTC-SG6/8 is suited for commercial AV installations where a square grille profile is required rather than a round one. It is specified for use with the JBL C328 and C277 ceiling speaker models.

This grille is sold as a single unit per package.
