These units have a 12" dial and the cases are available for flush or surface mount applications. Standard case finish is powder grey. Consult factory for other finish availability. The elapsed time indicator operates on 120VAC 60Hz and is controlled by a remote control panel (97ET). The 3 position switch starts, stops, and instantly resets the hands to the starting position. The 97ET Control Panel mounts to a single gang switch box. [Product Specs]
