Extron SMB 213 (part number 70-1142-33) — the white three-gang variant of Extron's SMB 210 Series surface mount box, holding three Flex55 or EU modules outside the furniture.

Specify this part when the table, lectern or wall is light-toned and a black enclosure would read as a blemish. Everything mechanical matches the black 70-1142-32: a 223 mm wide metal shell, high-impact thermoplastic end caps, a 30 degree working face and a rear slot 12 mm high running end to end. Two cable openings underneath let the three modules' cable bundles separate instead of crowding a single hole.

Key Capabilities

• Room for three gangs of Flex55 or EU connectivity in one white enclosure
• 223 mm W x 81 mm H x 82 mm D (8.78 in. x 3.20 in. x 3.22 in.)
• Light 0.3 kg (0.6 lb) assembly that will not overload thin table skins
• Two 25 x 44 mm cable openings plus a 12 mm full-width rear slot
• Installs free-standing, on the supplied wood screws, or on the optional SMB Table Clamp Kit
• Clamp option covers surfaces from 11 mm to 51 mm thick

Where It Is Used

Classrooms and lecture theatres with light casework, hospital and imaging department meeting rooms, hospitality boardrooms and higher-education collaboration tables. It is also a clean retrofit route when a room gains a third connectivity module and the existing table has no spare cutout.
