A low maintenance, dual action linear actuator suitable for systems requiring opening and closing movements.

Dual action carriages – Two or more carriages move in opposite directions symmetrically for systems requiring bi-parting opening and closing movements.

Herculane® wheel technology – DAPDU2 features the same Herculane® wheels that are popular in the PDU2 unit and give excellent load capacity and durability with quiet operation.

Low maintenance – The low friction synthetic wheels offer a long service life and are low maintenance as no lubrication is required.

Flexible – With multiple sizes and configurations including a choice of drive options, flat or angled carriage plates for easy mounting and multi carriage arrangements for wider door applications, DAPDU2 is versatile to fit the application needs.
