Extron MMK 3 (part number 70-1264-32) — black mullion mount kit for the Extron TLS 1025M scheduling panel.

This is the widest member of Extron's MMK 1, 2 and 3 trio, cut for the TLS 1025M and fastened to the vertical frame beside a door. Installation follows the same short sequence as its smaller siblings: two 1/8 in pilot holes, one cable pass-through of 5/8 in maximum diameter, then the panel hooks onto the mounting plate and a magnetic cover plate closes the assembly. An LED overlay is supplied for the room-side view.

Key Capabilities

• Carries the Extron TLS 1025M TouchLink scheduling panel on a door mullion.
• Metal bracket of 4.08 in H x 8.54 in W x 0.71 in D (104 x 217 x 18 mm) weighing 0.55 lbs.
• Includes an LED overlay so the inside-facing side of the install stays visually quiet.
• Holds protrusion under 4 inches from the outer mullion face for ADA compliance.
• Status LEDs stay legible from both approaches to the room.
• Black matte finish; Extron lists the aluminum matte version as part 70-1264-38.

Where It Is Used

Executive boardrooms, divisible training suites, research-institute meeting rooms and hospital administration floors — anywhere a larger scheduling display has to sit on the door frame because the wall around it is glazed. The published Extron template keeps hole placement uniform across a whole floor of rooms.
