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.
Before You Order
The 22 System is a configured product. Confirm the following before ordering — these are the questions our team fields most often.
A mounting plate is required. Every device installs into a 22 System mounting plate. Devices cannot be installed into a standard junction box alone. Single device = single plate. Two devices = double plate.
Drywall uses a single barrel size (Short). The three-depth logic (Short / Medium / Long) applies only to multi-material installations. If you are installing into drywall, barrel length is not a choice.
Depth cannot be adjusted after installation. Once the finish material is installed, the barrel depth is fixed — unless the wall is accessible from behind. Confirm material thickness carefully, especially for stone, tile, and millwork.
The Keypad Control is not a standard on/off switch. It is a momentary smart-home control requiring a low-voltage data connection and a compatible home automation system. It does not replace a line-voltage switch.
GFCI is not available within the 22 System. For code compliance in wet locations, install an upstream GFCI breaker at the panel. Consult a certified electrician.
How It Installs
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. Drywall installations use a single barrel length (Short, 6.35 mm / ¼").
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 Selecting the Right Barrel Depth.
Device Configurations
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.
Stacking two single devices: Two single mounting plates can be installed adjacent to one another — vertically or horizontally — to create a two-device layout across separate junction boxes. For a single-plate integrated look, specify a Double Linear or Double Linear Wide instead.
| Configuration | Devices | Center-to-Center |
|---|---|---|
| Single | 1 | — |
| Double Linear | 2 | 1.8" (45.8 mm) |
| Double Linear Wide | 2 | 2.8" (71 mm) |
| Double Diagonal | 2 | 1.8" (45.8 mm) along axis |
Available Devices
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.
Type G (UK / international) and other regional socket standards are not stocked by Casson. Contact Bocci directly for international device availability.
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. Functions as a momentary control — not a standard line-voltage on/off switch. Programmable via a low-voltage CAT5 data connection, and 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.
Selecting the Right Barrel Depth
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. For multi-layer walls (e.g. ½" plywood substrate behind ¾" stone), add the layer thicknesses together and select by total depth.
| Material Thickness | Select | If Between Sizes |
|---|---|---|
| Up to 6.35 mm (¼") | Short | — |
| 6.35–19 mm (¼"–¾") | Medium | Select Medium; shim hard materials up, or machine soft materials down |
| 19–31.75 mm (¾"–1¼") | Long | Select Long; shim hard materials up, or machine soft materials down |
| Over 31.75 mm (1¼") | Not supported | Contact us |
Availability by depth: Short is available for all device types. Medium and Long are available for selected components — confirm before ordering.
Depth is fixed once installed. Barrel depth cannot be changed after the finish material is in place unless the wall is accessible from behind. For stone and tile, confirm material thickness before ordering.
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.

Tools & Accessories
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. Multi-material installations only — not used with drywall. Must be specified at time of order and accounted for during finish material preparation; cannot be retrofitted to a completed installation.
Lead Time
Standard lead time is 1–2 weeks from order confirmation. Rush production is available for an additional $50 CAD — request in your order notes or at checkout. Data & Control devices (CAT6A, Coaxial, Telephone, Keypad Control) may require additional lead time; confirm at time of quote.
