DDO 500


Direct Drive Motors are used for installations that do not require anti fall back devices. These are typically industrial roller doors and grilles, non-counter balanced and vertical lift doors.
The DDO 500 is equipped with a choice of mechanical or digital limits and a low-level haul chain to be used in the event of a power failure to open or close a door.
The DDO 500 has a 40mm bore diameter.
