Extron MMK 5 – Mullion Mount Kit for TLS 835M, Black

Product Overview

MMK 5 (Black), part number 70-1333-22. The Extron MMK 5 is a mullion mount kit for scheduling panels, built specifically for the 8 inch TLS 835M. It attaches the panel to the vertical frame separating a door opening from the adjacent glass wall, which is typically the only mounting surface available in a glass-fronted meeting room. The low-profile design projects less than 4 inches from the mullion and leaves the panel's side LED status indication visible from both approaches. Black and aluminum matte finishes are available to match common door frame systems.

Product Description

Glass-fronted rooms leave nowhere to put a scheduling panel except the mullion. That frame member is narrow, often structural, and visible from both inside and outside the room, so the mount has to be dimensionally correct and visually restrained. The MMK 5 is designed for that condition and sized for the TLS 835M specifically.

Projection from the frame is under 4 inches, which keeps the installed panel within ADA protrusion limits for objects in circulation paths. In a corridor lined with meeting rooms, that constraint applies to every panel, so it is worth confirming during design rather than at inspection.

From outside the room, the mount's proportions are intended to blend with the panel and the mullion rather than read as separate hardware. The panel's edge LED indication stays visible on both sides after mounting, so someone walking the corridor still gets room status without stopping to read the screen.

The kit ships in black or aluminum matte to match door hardware and storefront framing. Where the panel needs upward tilt to read properly at ADA mounting height, add the optional MMK 5/6 Angle Brackets. For the larger 10.1 inch Extron TLS 1035M, specify the MMK 6.

Key Features

• Purpose-built for the TLS 835M — Sized and engineered specifically for the Extron TLS 835M 8 inch scheduling panel.
• Mounts to the door mullion — Secures the panel to the vertical frame between the door and adjacent glass in glass-fronted rooms.
• Low profile — Projects less than 4 inches from the mullion frame, keeping the installation within ADA protrusion limits.
• LED status stays visible — Panel edge LEDs remain visible after mounting so corridor-level room status is preserved.
• Two matched finishes — Black and aluminum matte options to match door hardware and storefront framing.
• Optional angle brackets — Accepts MMK 5/6 Angle Brackets for upward tilt at ADA-compliant mounting heights.

Frequently Asked Questions

Which panel does the MMK 5 fit?

The Extron TLS 835M, the 8 inch wall mount TouchLink scheduling panel. The 10.1 inch TLS 1035M requires the MMK 6.

How far does the mounted panel project from the frame?

Less than 4 inches, which is designed to keep the installation ADA compliant in circulation paths. Verify final installed height and location against your local code review.

Are the panel status LEDs still visible?

Yes. The mount is designed so the LEDs on either side of the panel remain visible after installation.

What finishes are offered?

Black (70-1333-22) and aluminum matte (70-1333-28). Both are functionally identical; select to match the surrounding door frame.

Can I tilt the panel upward?

Yes, using the optional MMK 5/6 Angle Brackets, sold separately in packs of five, which provide upward tilt at ADA mounting heights.

Does the mount work on any storefront system?

It is designed for typical commercial door mullions. Confirm mullion width and depth against the mount during design, particularly on custom or non-standard frame systems.
