SUSPENSION MOUNT
Usually used for DOUBLE SIDED DISPLAYS although SINGLE SIDED can also be suspended. They will hang down from a Gantry or Ceiling fixing and have chain rings bolted into the case top for the chains to be attached.
All digit sizes from the 2.3” to 18” may be suspension mounted, but most commonly digit heights of 6” and greater are used, where this size of DISPLAY is a requirement in a large space.
Dimensions of the case can be given once the digit height and number of digits across the display are known.
MULTI LINE LARGE DIGIT DISPLAYS
Most Large Digit displays in this series are SINGLE LINE, but MULTI LINE Large Digit displays are available and can be supplied with –
- Different Digit Heights on each line
- Different Input signal type on each line
- Different number of LED digits on each line
Multi line Large Digit displays can be FIXED WALL or SUSPENSION Mounting
