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.
