The TSW-770/1070-MUMK permits a TSW‑770, TSW‑1070, TSS‑770, or TSS‑1070 series touch screen touch screen to be attached to the mullion of an interior glass wall, window, or partition. The TSW-770/1070-MUMK mounts a compatible touch screen to the left or right of any hollow, metallic vertical mullion. Two mounting brackets are provided that allow the TSW-770/1070-MUMK to be installed in one of two configurations (side mount or front mount). Wiring is run to the touch screen from inside the mullion to create a clean, finished appearance. The TSW-770/1070-MUMK is ideal for mounting at the entrance to a meeting space for room scheduling applications, and it is compatible with the TSW‑770‑LB and TSW‑1070‑LB light bars to provide a clear indication of the room availability status.
