The LiftMaster DDO8900W Dock Door Opener, Light Duty, is a side-mount commercial jackshaft operator engineered specifically for loading dock openings. Designed for sectional dock doors with high-lift or vertical-lift track, it automates daily traffic at warehouses, distribution centers, and retail backrooms while adding smart access control. Integrated Wi‑Fi with myQ technology enables remote monitoring and operation, event alerts, and activity logs, making it a practical replacement or upgrade for facilities seeking greater visibility and control. Security+ 2.0 tri‑band radio offers reliable remote performance, and the compact jackshaft design frees ceiling space around dock levelers and lighting.
Built for light-duty commercial use, the DDO8900W runs on 120 VAC, 60 Hz input and drives a 24V DC motor for smooth start/stop operation that helps reduce door and hardware wear. Electronic limits and onboard diagnostics streamline setup, and the operator supports standard 3‑button control stations, key switches, and LiftMaster wireless controls. It meets UL 325 requirements and must be installed with monitored entrapment protection; it is compatible with LiftMaster monitored photo eyes and sensing-edge systems (e.g., CPS‑U/CPS‑UN4 and approved monitored edges). Installation is side-mounted to the torsion shaft of a properly balanced counterbalanced door; professional installation and compliance with all local codes and UL 325 are strongly recommended. myQ setup uses 2.4 GHz Wi‑Fi (802.11 b/g/n) for connectivity, while Security+ 2.0 remotes operate on tri‑band 310/315/390 MHz for dependable commercial dock operation.
