Bocci 22: Flush Outlet System

The most considered electrical outlet in architecture is one you cannot see. The Bocci 22 System is a flush-mounted electrical system designed by Omer Arbel that disappears entirely into the surfaces it serves, drywall, stone, tile, glass, millwork, and concrete, leaving no cover plate, no frame, and no interruption to the finish. It is the defining detail that separates a resolved interior from a standard one.

Where conventional outlets punctuate a wall with plastic hardware, the 22 System integrates. A cylindrical device locks into a mounting plate seated directly behind the finish material, its face flush with the surface. The result is an outlet that becomes part of the architecture, as precise and considered as the marble it sits in, the millwork it meets, or the plaster it disappears into.

Designed in 2009 and made in Vancouver, Canada by Bocci. UL-listed for installation in Canada and the United States. Honoured by Red Dot, D&AD, the German Design Council, and the Industrial Designer Society of America.

The 22 System installs in two ways depending on your wall surface. Both result in the same outcome: a device face flush with the finished wall, with no visible hardware of any kind.

Drywall — The mounting plate is embedded directly into the wall during the finishing process, mudded over and painted flush. The outlet emerges at the surface as though it was always meant to be there. No cover plate. No escutcheon. No trace of conventional hardware. Compatible with drywall, plaster, and wallpaper applications.

Multi-Material — For stone, tile, glass, millwork, MDF, Corian, and other solid substrates. The mounting plate is set behind the finish material before it is installed. The device locks through from the face, sitting precisely flush with the surface. Backsplashes, stonework, and millwork remain completely uninterrupted. Barrel depth must be matched to material thickness — see the Barrel Depth Selection Guide.

The 22 System is available in single and double configurations. Double plates are rotatable — they can be oriented vertically or horizontally to suit the installation.

Single — One device, one mounting plate.

Double Linear — Two devices in a tight vertical or horizontal stack.

Double Linear Wide — Two devices in a vertical or horizontal stack with wider spacing between positions.

Double Diagonal — Two devices set at an offset angle to one another. The mounting plate is rotatable to suit the desired orientation.

All devices are cylindrical, Ø 35 mm, and interchangeable within any 22 System mounting plate. Standard finishes (White, Black, Almond, Grey) are available across all device types. Heritage finishes are available for outlets and USB-C only — see Finishes below.

Outlets

• 15A Outlet — Type A/B, 120V, tamper resistant. The standard choice for most residential and commercial applications. Confirm amperage with your electrician if unsure.
• 20A Outlet — Type A/B, 120V, tamper resistant. Requires a dedicated 20A branch circuit. Specified for high-draw appliances or commercial applications.

USB & Media

• USB-A — 15W, dual port. For charging and device connectivity.
• USB-C — 45W, 100–240V, single port. Fast-charge compatible. Available in Heritage finishes.
• HDMI — Standard pass-through connector. For AV integration into millwork, conference rooms, or media walls.

Data & Control — Available on request. Lead times may vary. Contact us to confirm availability and pricing.

• CAT6A Data — RJ45. High-speed data connection for network integration.
• Coaxial / Cable — F Connector. For cable and satellite connections.
• Telephone — RJ12.
• Keypad Control — A minimalist smart home keypad, programmable via CAT5 connection. Compatible with leading home automation systems. Dimming functions can be programmed through a compatible smart home system — the 22 System does not include a standalone dimmer device.

For multi-material installations, the barrel depth of the device must match the thickness of the finish material. This is the most common point of confusion — and the most important measurement to get right before ordering.

Measure from the finished face of the material to its back edge. Then select the depth that matches, or machine/shim the material to reach one of the three standard depths:

• Short — 6.35 mm (¼"). Standard depth. Available for all device types.
• Medium — 19 mm (¾"). Available for selected components — confirm before ordering.
• Long — 31.75 mm (1¼"). Available for selected components — confirm before ordering.

If your material falls between two depths, select the next size up and machine or shim accordingly. Soft materials (hardwood, MDF) are typically machined down. Hard materials (stone, tile) are typically shimmed up. Refer to the Barrel Depth Selection Guide (PDF) for detailed guidance, or contact our team — this is a common question and we're happy to help.

Standard — Available for all device types.

• White — RAL 9016
• Black — RAL 9017
• Almond — RAL 1013
• Grey — RAL 7038

Heritage — Available for Outlets (15A, 20A) and USB-C only.

• Dove — Pantone 2333
• Carob — Pantone 7554

Custom colours are available for larger volume orders. Contact us for details.

22 System Removal Tool — Required for all installations, drywall and multi-material. Used to seat and eject devices from the mounting plate without disturbing the wall finish. One tool is sufficient per project site. Sold separately.

Router Template — Optional. For multi-material installations into wood, MDF, Corian, or stone. Used for alignment and as a routing guide. Compatible with a 36.5 mm (1-7/16") Forstner bit, guide bushing, or CNC.

Plaster / Tile Trim Cap — Optional. For multi-material installations into tile, grout, or plaster. Protects the device opening during installation of finish material. One per device required; reusable.

Decorative Trim Ring — Optional. A metallic ring that sits flush around the device face, adding a refined finish detail. Available in multiple finishes.

For larger volume orders. Contact us for details.

Are outlets tamper resistant?

Yes. All 22 System outlets bear the "TR" marking on the outlet face.

What junction box should I use?

Standard depth, minimum 54 mm (2⅛") deep. Must have two screw holes spaced 83 mm (±0.5 mm) apart in the middle plane from each edge.

Measure from the face of the finish material to the back of the substrate. Short = 6.35 mm (¼"), Medium = 19 mm (¾"), Long = 31.75 mm (1¼"). When in between, select the next size up. Barrel Depth Selection Guide (PDF)

Is there a GFCI outlet?

Not within the 22 System itself. For wet area code compliance, a GFCI breaker must be installed remotely in the panel (sourced independently). Consult a certified electrician.

Do I need the removal tool?

Yes — required for all installations (drywall and multi-material) to seat and remove devices. One tool is sufficient per project site. Purchase the Removal Tool.

Can I mix line voltage and low voltage on one plate?

Yes, provided the junction box is equipped with a permanent barrier or listed divider with separated raceway. See NEC 2008: Article 800.133 Exception #1 and Article 620.36.

What is the Keypad Control?

A minimalist keypad for smart home systems, programmable via CAT5 connection. Functions are set through your home automation platform. The keypad can also control dimming functions through a compatible smart home system — the 22 System does not include a standalone dimmer device.

Is the 22 System approved for New York City?

Yes. The NYC Department of Buildings issued an updated approval in June 2024 for use per manufacturer installation instructions. Contact us for documentation.

Is a practice installation recommended?

Yes — Bocci recommends a practice installation for anyone installing the 22 System for the first time. The system requires precise and skilled craftsmanship, particularly for drywall mud-in applications.
