Boxes & Brackets for Commercial ProAV Installations
Reliable mounting and junction hardware is essential to every commercial audio visual system. Windy City Wire’s Boxes & Brackets category brings together low-voltage junction boxes, cut-in boxes, ceiling grid hardware, handy boxes, extension rings, recessed cable plates, and device mounting brackets that simplify AV integration, speed rough-in, and support clean, code-conscious installs in any commercial environment.

Product types and when to use them
Industries and spaces that rely on ProAV boxes and brackets
Selection considerations for AV contractors and integrators
How these components streamline AV integration
Integrating with Windy City Wire workflow
When pulling cable to these junction boxes and brackets, SmartWire labeling and footage markers help installers stage, identify, and terminate circuits correctly at each device location. Using RackPacks for multi-cable pulls reduces snags and waste during rough-in, especially when feeding multiple knockouts or spanning long ceiling grid runs. The result is more predictable job timelines and cleaner turnovers.

Build consistent, serviceable AV infrastructure
Standardizing on proven ProAV boxes and brackets across projects helps AV contractors, facility managers, and consultants deliver cleaner installations, reduce installation time, and maintain clear documentation. From new construction to complex retrofits, these low-voltage accessories support dependable AV integration in commercial environments.
• New construction: Use 4-inch square welded junction boxes in the depth you need (1-1/2", 2-1/8", or 3-1/2").
• Existing hollow walls (retrofit/old work): Choose a 4-inch square, 2-1/8" deep “cut-in” box or a 3-1/2" deep 4-inch square box with old work clips and plaster ears for secure retrofit mounting.
• Suspended ceiling tiles: Select a 4-inch square junction box with a ceiling grid span bar for T-bar support and precise device placement.
• Identification requirements: A 4-inch square red junction box helps call out life-safety or priority AV circuits in the field.
• Other use cases: 4-inch octagon boxes suit overhead AV drops/fixtures, while handy utility boxes (1-7/8" or 2-1/8" deep) are great for compact surface-mount low-voltage terminations.
• Depth: Choose 1-1/2" for tight spaces, 2-1/8" for typical AV terminations, or 3-1/2" when you need more volume for adapters, pigtails, and higher cable counts. You can also add a 2-1/8" deep 4-inch square drawn extension ring to increase capacity without changing the box location.
• Knockouts: Match KO sizes to your conduit—common options include side patterns like (8) 1/2" and (4) 1/2"-3/4", and bottoms like (3) 1/2" and (2) 3/4". Combination 1/2"-3/4" KOs accept either trade size for flexibility.
• Planning tips: Verify conduit entry points (side vs bottom) for cable management, respect box/conduit fill requirements, and use bushing or grommet protection for low-voltage cable transitions.
• Drywall rings: One- and two-device opening mounting brackets for 1/2" or 5/8" drywall include screws for fast install; ideal behind displays, plates, and keystone frames. Price per ring—order 1 = 1 ring.
• Recessed pass-throughs: A one-gang recessed low-voltage cable plate provides a flush, bend-radius-friendly exit behind displays and credenzas.
• Ceiling support: A 24" T-Bar bracket centers and supports AV boxes in ceiling tiles for projectors, speakers, sensors, and APs.
• Capacity add-ons: Use a 4-inch square drawn extension ring to add depth and additional side KOs when device or cable count grows during change orders.
