Extron MMK 1 (part number 70-1264-12) — the black mullion mount kit that fixes a TLS 525M scheduling panel to the narrow vertical frame beside a door.

Glass-fronted meeting rooms rarely offer a wall for the scheduling panel. What they do offer is the mullion: the slim upright between the door opening and the adjacent glazing. This kit is made for exactly that surface. Two small screw holes and a single cable pass-through are all it needs, and once the magnetic cover plate is on, the assembly reads as part of the frame rather than an add-on.

Key Capabilities

• Holds the Extron TLS 525M 5 in wall mount TouchLink scheduling panel on a mullion frame.
• Metal construction measuring 3.78 in H x 6.64 in W x 0.71 in D (96 x 169 x 18 mm), weighing 0.30 lbs.
• Sits less than 4 inches proud of the outside face of the mullion, keeping the installation within ADA requirements.
• Leaves the panel status LEDs readable from either side of the frame.
• Black matte finish; Extron lists the same kit in aluminum matte as part 70-1264-18.
• Extron publishes a downloadable drilling template to speed up hole placement.

Where It Is Used

Corporate meeting-room floors, university seminar suites, hospital consult rooms and any interior fit-out where glass partitions leave no drywall next to the door. Installation calls for two 1/8 in pilot holes and one cable hole of 5/8 in maximum diameter through the mullion.
