Extron MMK 1 (part number 70-1264-18) — the aluminum matte version of Extron's mullion mount kit for the TLS 525M scheduling panel.

Where a door frame is the only mounting surface available, this kit turns it into one. The bracket fastens to the mullion with two sheet-metal screws, routes the panel cable through a single pass-through hole of 5/8 in maximum diameter, and finishes with a magnetic cover plate. The aluminum matte finish suits buildings that use brushed or anodized door hardware, where a black bracket would draw the eye.

Key Capabilities

• Carries the Extron TLS 525M 5 in wall mount TouchLink scheduling panel on a mullion.
• Metal bracket of 3.78 in H x 6.64 in W x 0.71 in D (96 x 169 x 18 mm) at 0.30 lbs.
• Protrusion stays under 4 inches from the outer mullion face, satisfying ADA accessibility rules.
• Panel LED indicators stay visible from both approaches to the door.
• Aluminum matte finish; the black equivalent is Extron part 70-1264-12.
• Backed by 3 years parts and labor, with CE, RoHS and WEEE compliance.

Where It Is Used

Glazed conference rooms, executive suites, clinical consult rooms and training centers where the scheduling panel must sit beside the door and the surrounding surface is glass rather than plasterboard. Fleet rollouts benefit from the downloadable Extron template, which keeps hole placement identical from room to room.
