National Time offers Style 040 Open-Faced clocks to create a complete clock system product line. The 040 series movements will complement today's architectural treatments and are ideal for offices, lobbies, or even outdoor decoration. The movements are mounted flush with the wall surface, and the markers or numerals are mounted to the wall. The markers have a minimum thickness of 1/4" and include projecting spurs for mounting into small holes with mastic. Consult factory for custom marker styles and mounting. The 040 series is offered as a 120VAC non-corrective clock, a 120/24VAC corrective system clock, or a 24VDC Rotary Drive system clock. Large movements have a 10 times speed correction or can be corrected automatically with a clock controller. See our Architectural Clock section. Standard finishes available for the hands and markers are white, black, and powder gray. Other finishes including anodizing are supplied on special order.
