Extron SMB 212 (part number 70-1142-22) — the two-gang, black member of the SMB 210 Series, sized for a pair of Flex55 or EU modules mounted on the outside of a surface.

When a room needs two connectivity modules at the table but the furniture cannot be cut, this enclosure supplies the pocket. Its 5.99 in. wide shell holds two gangs side by side, angled 30 degrees back from vertical so plugs seat cleanly and cables fall away from the user. Extron builds the shell from metal and caps the ends in high-impact thermoplastic, and a black finish keeps it discreet against dark laminate and veneer.

Key Capabilities

• Two-gang capacity for Flex55 plates or EU modules, including powered devices like button panels and transmitters
• 5.99 in. W x 3.20 in. H x 3.22 in. D shell (152 x 81 x 82 mm), 0.4 lb (0.2 kg)
• One 1.00 in. x 1.75 in. cable opening (25 x 44 mm) for the pair of modules
• Rear slot 0.46 in. high (12 mm) spans the full width so cable can run flat to the surface
• Sits loose, screws down with the included hardware, or clamps with the optional SMB Table Clamp Kit
• Clamp option accommodates surfaces 0.38 in. to 2.00 in. thick (11 to 51 mm)

Where It Is Used

Boardroom and conference tables, classroom instructor stations, lecture hall lecterns and training rooms — anywhere two modules of connectivity or control need to appear on a finished surface. The black finish suits dark furniture in control rooms and command centers where a white box would draw the eye.
