The WMKU-4SM EX ands the wall box mounting options available for a TPMC-4SM or TPMC-4SMD Touch Screen. It is also compatible with TPCS-4SM and TPCS-4SMD Touch Screen Control Systems. It enables installation of the touch screen device over a vertically-oriented 1-gang or 2-gang electrical box[1], or a 2-gang UK (BS 4662) electrical box. It can also be used to surface mount the touch screen without a box, requiring just a small cut-out[1].
Minimal impact is made to the touch screen's thin profile and contoured appearance. Using the WMKU-4SM, the touch screen protrudes less than 7/8 inch (21 mm) from the wall surface, and the overall height is increased slightly to 4 inches (102 mm).
