McGrath A210 – 35mm Backset – Euro Mortice Back-to-Back Smart Lock
The McGrath A210DB is a slimline double-sided 5-in-1 digital smart lock offering all the functionality of the standard A210, with the added benefit of access control on both sides of the door. It is engineered specifically for narrow stile aluminium doors, making it suitable for residential, office, and commercial environments.
Lock functions are managed through the McGrath Locks App using Bluetooth as standard. Access can be granted via PIN codes, RFID credentials, fingerprint recognition, Bluetooth eKeys, or mechanical key override. Optional Wi-Fi connectivity can be added via a compatible McGrath Locks gateway for remote access and monitoring.
Usually same day if ordered before 11am AEST (excluding weekends and Qld public holidays)
This model is also available in a single-sided configuration, suitable where access control is only required from one side of the door.
