Extron V-Lock Wall Bracket (part number 70-534-03) — white replacement V-Lock wall assembly, sold as a pair, for the System INTEGRATOR SI 26 and SI 28 two-way surface mount speakers. Extron lists this part as retired.

This is the white-finish equivalent of 70-534-02 and supplies only the parts that stay on the wall: the plate and the locking stage that holds the V-lock groove. Its value is in what it lets an installer avoid. Conventional brackets require the speaker to be held aloft while fixings are tightened behind it; V-Lock separates the two operations entirely. The plate is anchored on its own — the stage swings 90° clear so the screws are accessible — and cable is dressed through the access hole before the speaker ever leaves the floor. The SI 26 then drops straight into the groove; the SI 28, being the larger cabinet, hooks one edge, swivels, catches the second edge and slides down. A hex cap screw hidden under the Extron logo sets and locks the final angle.

Key Capabilities

• White wall plate and locking stage for SI 26 and SI 28 speakers.
• Two individual mounting kits per pack, one per speaker, with an Allen hex tool.
• Wall plate offers three primary and four secondary mounting holes.
• Locking stage swings 90° clear of the fixings during installation.
• Integral wiring access hole for concealed cable entry.
• Seismic safety cable can be reattached to the speaker.
• Concealed hex cap screw sets the angle and locks the speaker to the mount.

Where It Is Used

Existing SI 26 and SI 28 estates in light-finished rooms — school and college classrooms, healthcare and civic buildings, hotel meeting space — typically bought as a service spare when an original bracket has been damaged or when the speakers are being repositioned during a refurbishment.
