We upgraded an antiquated Allister trolley opener with a new LiftMaster WiFi chain drive trolley opener, complete with a 7-foot chain drive rail and all necessary components for smooth, reliable operation.

In addition, we replaced damaged torsion cables and a missing roller, repaired the damaged track, and lubricated all moving parts to ensure long-term performance. A perforated angle was also added to the top panel, in compliance with the opener warranty, for secure and proper installation.

This comprehensive service improves garage door functionality, safety, and longevity, leaving the system operating efficiently and reliably.
